Answer 1

First you need to find the length of the side of the smaller triangle. To do this, you would use the Pythagorean theoem.

Answer 2

this is the case of altitude theorem in case of a right triangle when the altitude is from the right angle on hypotenuse - do you know it ?

Answer 3

so using it you get

h^2 = x*4
10^2 = x*4

100 = 4x divide both sides by 4

100/4 = x

x = 25
