Exercise 11 Page 495

To find the missing side of the triangle, we will use the Pythagorean Theorem. a^2+b^2=c^2 In the formula, a and b are the legs and c is the hypotenuse of a right triangle. We are given a triangle with a=65, b=72, and c=x.

Let's substitute these values into the formula and solve for x. Since a negative side length does not make sense, we only need to consider positive solutions.
