Question

What’s the missing side length in this right triangle?

Answer 1

A: 15

Explanation:

It is asking for the hypotenuse of the triangle. To find this, use pythaogreans theorem.

A^2 + B^2 = C^2

In this case,

9*9 + 12*12 = C*C

81 + 144 = C*C

225 = C*C

Now do the square root of both sides and you get

15 = C. Therefore the missing length is 15.
