The theorem I think we need is this one: Theorem: If an altitude is drawn to the hypotenuse of a right triangle, either leg of the triangle is the geometric mean between the length of the hypotenuse and the segment of the hypotenuse adjacent to that leg.

go on

9. Directrix

Go ahead. I was just writing up a drawing for this problem.

@sharon_penn I'm waiting for you to say something about solving the equations on the attachment.

12. Directrix

I know how to do this and will help if you will just tell me what your thinking is on the problem.

13. sharon_penn

My thought was that the sides would equal so I thought that the answer x=2sqrt3 y=4 was correct

14. sharon_penn

am i right?

15. Directrix

I'll work the equation here. y/12 = 28/y y = 4*sqrt(21)

16. sharon_penn

awesome

17. Directrix

16/x = x/28 x = 8*sqrt(7)

18. Directrix

Is that what you got?

19. sharon_penn

no but I see how you got it :)

20. Directrix

Okay. Learn those Geometry theorems. :)
