One leg of a right triangle is 12, and the hypotenuse is 20. The length of the other leg is ___

The answer is 16.

Step-by-step 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

for the points! : )

the correct is answer is a 9-sided polygon!
