Question

in a right triangle, the length of a hypotenuse is 20 inches and the length of one leg is 15 inches. what is the length of the other leg in inches

Answer 1

You'll have to use the Pythagorean theorem:

$c^{2} = a^{2} + b^{2}$

In your case:

$c^{2} = 20^{2} + 15^{2}$
$c^{2} = 400 + 225$
$c^{2} = 625$
$c = \sqrt{625}$
$c = 25 inches$


Answer:

$\boxed{\bf~The~answer~is~25~in.}$


Hope it helped,
