Question

How do you find the missing side of the right triangle with legs: a = 15, b = 20?

Answer 1

There are two cases one is `c=25` and the other `c=5sqrt7`

Explanation:

Hence its a right triangle we can apply pythagoras theorem so

let a,b the sides of the right angle hence the hypotenuse is

`c^2=a^+b^2=>c^2=20^2+15^2=>c=25`

But b=20 could be also the hypotenuse of the right triangle hence

`20^2=15^2+c^2=>c=5sqrt7`
