**Steve**, Friday, November 18, 2011 at 1:05pmThis looks familiar, but I can't find the post where it was solved. So, here goes again:

If the distance from the building to the point on the ground is d, and the height of the building is h,

h/d = tan 39

(h+60)/d = tan 48

or,

d = h/tan 39 = (h+60)/tan 48

h/.8097 = (h+60)/1.1106

1.235h = .900h + 54.025

.335h = 54.025

h = 161.27
