Pythagorean Theorem Formula: a² + b² = c²

9² + 13² = x²
81 + 169 = x²
250 = x²
square root of 250 = 15.8
15.8 is already rounded.

8² + b² = 12²
64 + b² = 144
144 - 64 = 80
square root of 80 = 8.9
8.9 is already rounded.

10² + 12² = x²
100 + 144 = x²
244 = x²
square root of 244 = 15.6
15.6 is already rounded.

I am currently working on this in my class so I have this fresh in my mind.
Hope this Helps!!
