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 = √(625)`

`c = 25 inches`


Answer:


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