Answer 9.75 ft Reason Using the Pythagorean theory, a^2 + b^2 = c^2 (the hypotenuse) Since we know the diagonal measurement (the hypotenuse) we will call c=12 We know one leg is 7, so we will call b=7 Now we will solve for “a” Changing the equation to subtract c^2 - b^2 = a^2 Substitute in our numbers 12^2 - 7^2 = a^2 144-49= a^2 95 = a^2 Take square root of both sides
9.746 = “a” the unknown length Round to nearest hundredth 9.75
