2)A right triangle has a hypotenuse of length 15 and a leg of 9. what is the length of the other leg of the triangle?

Answer 1

5,5

Explanation:

5,5

Answer 2

A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum:
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs
15^2=9^2+B^2
225=81+B^2
225-81=B^2
144=B^2 (square root both sides)
12=B
