Answer 1

Hey there.

Remember the rule of 3/4/5: A^2 + B^2 = C^2; essentially the Pythagorean Theorem. Let's use our A side as 18 and our B side as 24.

18^2 + 24^2 = C^2
Simplify the squares.
324 + 576 = 900

C^2 = 900
Square root each side.

C = 30.

Your missing side length is 30. I hope this helps!
