The Pythagorean Theorem can be used to find the missing side length of a triangle when two other side lengths are known.

Consider the following measurements.

a=20
b=?
c=29
Use the formula c=a2+b2−−−−−−√, a modified version of the Pythagorean Theorem, to find the missing side length, b.
What is the value of b?
