Question

Using the Pythagorean Theorem, how do you find the length of a leg of a right triangle if the other leg is 8 feet long and the hypothenuse is 20?

Answer 1

Length of other leg of right triangle is `18.33` feet

Explanation:

According to Pythagoras theorem, in a right angled triangle, the square of hypotenuse is equal to the sum of squares of other two sides.

Here in the right angled triangle, hypotenuse is `20` feet and one side is `8` feet,

the other side is

`sqrt(20^2-8^2)=sqrt(400-64)=sqrt336`

= `sqrt(2xx2xx2xx2xx3xx7)`

= `4sqrt21=4xx4.5826=18.3304` say `18.33` feet.
