Question 431701: I want to make sure I'm doing this right. Here are the instructions.
Let A & B represent the lengths of the legs of a right triangle and let C represent the length of the hypotenuse. Find the unknown length.
A=3, C=5
This is what I got.
3^2 + B^2 = 5^2
9 + B^2 = 25
3 + B = 5
B = 5 - 3
B = 2
Is this right?
