use the pythagorean theorem, which says that the length of the hypotenuse is equal to the square root of the sum of the squares of the sides, like this:
:
sqrt(60^2+45^2) = 75
to solve yourself using your calculator, first inside the parenthesis solve the powers and add the products, then take the square root of the sum you got.
