If the height of the building (above S) is h, and the distance from ST to the building is x, then we have
h/x = tan60°
(h-10)/x = tan 30°
Rearrange things a bit and you have
h cot30° = (h-10) cot60°
Now just solve for h.
h/x = tan60°
(h-10)/x = tan 30°
Rearrange things a bit and you have
h cot30° = (h-10) cot60°
Now just solve for h.
