Use the Pythagorean’s Theorem to find the missing side of each triangle

131 is prime. So the answer is A

Step-by-step explanation:

Remark

x is one of the legs. The other one is √65

Equation

x^2 + (√65)^2 = 14^2

Solution

x^2 + 65 = 196                 Subtract 65 from both sides

x^2 = 196 - 65

x^2 = 131                          Take the square root of both sides.

√x^2 = √131

x = √131
