Question

Find the length of the altitude drawn to the hypotenuse. I got to the end and got 105 but do I square root it or leave it as is? Figure is below.

Answer 1

I think you would square root it, not very sure.

Answer 2

I thought the same thing, but I'm not sure as well

Answer 3

use similar triangles
15 /altitude = altitude / 7

altitude ^ 2 = 7*15 = 105
altitude = sqrt 105
