    pythagorean theorem 7^2 + b^2 = 13^2

    b^2 = 169- 49 = b = square root of b^2

    so b^2 = 120 to get b take the square root

    @triciaal i got 120 but you said so b^2 = 120 to get b take the square root. so i got lost :( sorry

    that example is showing how to use pythagorean theorem in that example the sides are 3 and 4 so the missing length was the hypotenuse 5 cm in your problem you have the hypotenuse and one leg so you subtract to find the other leg

    think of square root as the opposite operation to square just like addition with subtraction and multiplication with division

    had computer problems guess that was a sign not to post what I wrote bottom line is I don't get mad when a person needs time. I am extremely patient. I don't appreciate people who say " i don't understand" when they are not trying or reading.

    Math is fun. I think the key is to practice problems so you know the steps to follow and how to identify different theorems etc.
