You have to draw a picture to see what's going on. Once you draw the picture, you see there are 2 right triangles.

tan 56 = x/(20 + y) where y is the distance between the foot of the tower and the first point, and x is height of tower.

and tan 63 = x/y.

Now you have 2 equations and 2 unkowns, so you can solve it.

Repost if you need more help.

thanks!

you're welcome
