Find the missing variables

The triangle on the image is a right triangle which means we can use trigonometry to untangle its mysteries.

We have a side an and angle from that we can compute anything.

We will first compute x, we do so by taking the cosine of an angle,

Then we can also compute y, simply by using pythagorean theorem,

.

So triangle has sides which is also known as equilateral triangle.

Hope this helps :)

the answer is 62

i just took the test, the correct answer is .. 31.5 in.
