Question

Using the technique in the model above, find the missing side in this 30°-60°-90° right triangle.



Short = 5 , hypotenuse = 10
Long =

Answer 1

In 30-60-90 triangles, the:

Hypotenuse = short side * 2

Longer leg = short side * √3

So since you are solving for the longer leg, multiply the shorter leg by √3.

5 * √3 = 8.66

Longer leg = 8.66
