Question

One leg of a right triangle is 12, and the hypotenuse is 20.

The length of the other leg is ___
​

Answer 1

The answer is 16.

Explanation:

To solve you need to use Pythagorean Theorem. a^2 + b^2 = c^2 .

12^2 + b^2 = 20^2

144 + b^2 = 400

400 - 144 = 256

b^2 = 256

Next we need to take away the power of 2.

√256 = √b^2

√16 x 16 = √b * b

b = 16

Answer 2

i believe it is 16.

hope this helped :)
