Question

I need help with 14 and 15!?

Answer 1

15

Explanation:

Pythagorean theorem states that the hypogenous of a right triangle is
`c=\sqrt{a^(2)+b^(2)}` . The hypogenous is the longest part of the triangle which is directly across from the 90 degree angle.

a = 9

b = 12

so,

`c = \sqrt{9^(2)+12^(2) } = 15`
