Which equation can be solved to find one of the missing side lengths in the triangle?

The pythagorean theorem states that a^2+b^2=c^2 in a right triangle where c is the longest side. this equation can gelp you figure out the length of one side if you have the lengths of the other two sides.

example:
1. replace the variables in the theorem with the values of the known sides.
32^2+b^2=183^2

2. square the measures, and subtract 1,089 from each side.
1,089+b^2=33,489
b^2=32,400

3.find the square root of each side.
square root of b^2= squre root of 32,400
answer: b=180
