i have to find the value of x and y, how?

Use the theorems: One: If an altitude is drawn to the hypotenuse of a right triangle, the altitude is the geometric mean between the segments of the hypotenuse. So, 20 is to x as x is to 5 20/x = x/5 x^2 = 100 x = 10 -->The -10 root is not applicable here.

Theorem Two: If an altitude is drawn to the hypotenuse of a right triangle, either leg of the triangle is the geometric mean between the segment of the hypotenuse adjacent to that leg and the entire hypotenuse. So, 20 is to y as y is to 25. y^2 = 20*25 y = 10√5
