Question

Find the value of each variable.
30°
12
y
X

Answer 1

x = 6

y = 6√3

Explanation:

The shape shown in the image is a special right triangle with angle measures as follows:

90°-60°-30°

And side lengths represented with:

2a-a√3-a respectively to the angle measures.

• Given the side length that sees angle measure 90°, hypotenuse, is 12.

So that means,

2a = 12

and

a = 6
