A right triangle has side 9 and hypotenuse 15. Use the Pythagorean Theorem to find the length of the third side.

Provide your answer below:

Answer 1

12

Explanation:

Pythogorean Theorem:

a squared + b squared = c squared

9 squared or 81 + ? squared = 15 squared or 225

Inverse Pythagorean Theorem:

c squared - a squared = b squared

225 - 81 = 144

sqrt (144) = 12

12 = b
