Answer 1

C. 9 m

Explanation:

The Pythagorean theorem says

`leg_(1) ^(2) + leg_(2) ^(2) = hyp^(2)`

Let the third side, which is a leg, = x

`12^(2) + x^(2) = 15^(2)`

144 +
`x^(2)` = 225

`x^(2) = 81\\x = √(81) = 9`

C. 9 m

Answer 2

Answer: C— 9 m

Steps:
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 81
b = 9
