Answer 1

O The three lengths of a triangular sail are 12 feet, 16 feet, and 20 feet.

This one.

Explanation:

By doing Pythagorean theorem, you know a^2 + b^2 = c^2

So, do 12^2 + 16^2 = 20^2

Which simplifies down to 144 + 256 = 400

400=400, which is a true statement.

The rest of these questions do not follow Pythagorean Theorem, so this is the correct one.
