Problem 1 (on the left)

-------------------------------

Explanation:

The converse of the pythagorean theorem can be used to determine what kind of triangle we're dealing with.

Here are 3 important rules to have in your notes:

The third rule is probably the most familiar as it's the pythagorean theorem itself.

In this case, we have larger than , which fits the first rule mentioned.

=========================================================

Problem 2 (on the right)

-------------------------------

Explanation:

We follow the same idea as problem 1. This time, both and result in the same value (289). Therefore, is a true equation, and we go for the third rule mentioned earlier. An 8-15-17 right triangle is one of the infinitely many pythagorean triples.

b is the final answer! : )
