Answer: x = 25
===================================================
Work Shown:
We'll use the pythagorean theorem
a^2 + b^2 = c^2
7^2 + 24^2 = x^2
49 + 576 = x^2
625 = x^2
x^2 = 625
x = sqrt(625)
x = 25
The hypotenuse is 25 units long.
Note: the value of c is always the hypotenuse, while the order of 'a' and b doesn't matter.
