First you want to find X using the identities given for a 45-45-90 triangle. When comparing the triangles in the video, we find that X must be 6. Next, use the identity to solve for the measurements of the sides of the triangle. In the video example, 6 is the length of the two sides and 6 times the square root of 2 is the length of the hypotenuse. The video is very short and does not explain a lot of things in detail, but that is because the examples are easy to figure out.
This video explains to you how to find the area of a square. The area of a square is given by the formula
To find the length of a side of a triangle using cosine, you first need to find the angle and which sides are given. After you determine the angle and given sides, you'll need to figure out which trigonometric ratio to use. If you are given the adjacent side and the hypotenuse, you need to use cosine to solve. The degree equals adjacent divided by hypotenuse. In the example, Cos 39=3.5/x. After simplifying the equation, we found x to be 4.49. If the directions ask you to round, be sure to rou...
In this tutorial the author shows how to find out the missing side of a triangle which is similar to an other triangle. He explains the concept of similar triangle using diagrams and by showing that similar triangles have equal corresponding angles and parallel sides. Now he labels sides of similar triangles and intends to find out the length of unknown side. Now in similar triangles, as the lengths of sides are proportionate he shows how to write a equation of proportion and solve it finding...
For people who are learning geometry and would like to be able to find the perimeter of a rectangle, this video provides and quick and simple tutorial which provides the formula as well as a good example. The formula for finding the perimeter of a rectangle is simple the sum of all sides, or l+l+w+w, where l is the length and w is the width of the rectangle. After attaining the values of the length and width of the rectangle, you can simply plug in the values to this equation in order to find...
The first thing you have to do is draw a line of the same length as the radius of the circle you want to draw. Then, open the compass the same size as the line length you draw is. Rotate the compass and you will create a circle. Please note that drawing this on a single sheet of paper can be difficult because the paper can move. Also, you can try rotating the paper, instead of the compass.
Short homemade video showing how to make a Friendship Flip Flop Zig Zag bracelet. The bracelet is easy enough to be made by a child and the tutorial easy enough for a child to follow. The bracelet is made of knotted cotton strings. The bracelet can be made from 2 to as much different colors as you want, the more colors you use, the wider the bracelet is. Length of the bracelet can be adjusted by choosing the right length of cotton at the beginning.
In this tutorial, the instructor shows how to do a translation in geometry. Now he shows this by using various drawings and by practically explaining it while performing the translation. He first shows how to set up the translation line and now goes on to translate each and every vertex by drawing a parallel line to the translation line through each vertex, which is the same length as the length of the translation line. Now he combines the end points of the translated lines which gives us the...
The video teaches the viewer how to find the area of a parallelogram and the area of a triangle. For a parallelogram, the first step is to find the right angle, the line perpendicular to the base (this is a line you draw, not part of the parallelogram). The height of the line that forms this right angle with the base is the perpendicular height. Next, find the length of the base. The area is the base times the height. For a triangle, find the right angle with the base (again a line you draw)....
We've seen leggings look great and we've seen leggings look absolutely terrible (girls, wearing leggings with a short vintage t-shirt is NOT hipster cool. Just way too much exposure from the back, especially if you don't have a model's body).

Ah, the sand between your feet, the sun on your skin, and the debt you're accumulating. However strong my sense of wanderlust may be, I still can't justify dropping thousands of dollars on a vacation. Fortunately, a new site — Wander — promises to help you book vacations that match your budget.
While it might be a little past its prime now, the running gag about Nokia phones never breaking was one of the internet's favorite jokes. "If you buy one," they would say, "you'll never need another phone again." I think if those users could see into the future, they'd change their tune, as the Nokia 6 is now available to preorder — and I'm guessing it would give any of Nokia's old bricks a run for their money.
Just like a rapper engaged in tweet feud, Elon Musk was working overtime on Twitter this morning, dropping information about the upcoming Tesla Model 3. He even gave a sneak peek of the "release candidate" version of the car, sharing a brief clip of the car driving, which, let's be real, doesn't really tell us anything. Aside from the video, Musk also revealed the fun fact that the car gots its name after Ford sued Tesla for trying to name it the Model E, which would make the abbreviation of ...
Samsung's Gear VR headset is a thing of beauty; unfortunately, it only works with the Samsung Galaxy Note 4. That's where ImmersiON-VRelia's Head-Mounted Displays come in to play. With four different HMD models, we got a hands-on look at "The Go," which is not only affordable (at $125), but also compatible with the majority of Android and iOS devices.
Rooting your phone is one thing, but to truly be in control of your device, you need to be S-Off. S-Off allows you to flash, mod, and tweak just about any aspect of your phone, including the ability to run custom recoveries and flash kernels, which are vital tools for power-users. Up until now, there have been many ways to S-Off your device, but some newer HTC models have become un-exploitable.
No one likes to think about the possibility of natural disasters, but we all know they could happen at any time. Some of us are a little more paranoid than others, but wouldn't it be nice to know that you'd be protected if anything really crazy ever happened? Like the zombie apocalypse?

This video tells us the method to make a hair bow from a duct tape. You will need a duct tape, scissors and a bobby pin for this purpose. First take a sufficient length of duct tape. Fold it along the breath so that the sticky sides stick to one another. Now we get a duct tape in the shape of a rectangle. Fold the duct tape along its length. This forms a crease at the middle of the duct tape. Fold each half of duct tape along the length to the crease at the middle. This forms two creases at t...

A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.
