Question

Help picture below problem 16

Answer 1

The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.

     *look at the image I attached for a better explanation

By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation

    $?^2+9^2 = 16^2\\?^2 + 81 = 256\\?^2 = 175\\? = 13.2$

Thus the missing side length is 13.2 cm

Hope that helps!
