Question

For a right triangle with one leg = 3.24 cm and a hypotenuse = 7.16 cm, find the length of the missing leg

Answer 1

`a=√(40.768)`

Explanation:

Given a leg and a hypotenuse we can find the third side by substituting the known values using Pythagorean theorem, let the unknown be a.

`a^2+3.24^2=7.16^2`

Now all we must do is solve for a:

`a^2+3.24^2=7.16^2\\a^2+10.4976=51.2656\\a^2=40.768\\a=√(40.768)`
