Answer 1

Answer:

Hypotenuse or $c = 75$ in.

Step-by-step explanation:

The Pythagorean Theorem is as follows:

$a^2 + b^2 = c^2$ (We know the length of the legs, or a and b, so we can use the formula to find the length of c, or the hypotenuse)

$c^2 = 21^2 + 72^2$    (Simplify)

$c^2 = 5625$    (Take the square root of both sides)

$c = 75$ in.
