Question 1135713
draw this and there is a triangle with angle A, the complement of the 52 degree elevation, so 38 degrees; B, which is 90 degrees plus 34 degree elevation so 124 degrees; and C, at the top of the other building, which is 18 degrees. sin 18/60 as sin 124/b
Therefore 60 sin 124=b sin 18
and b=60 sin 124/sin 18 or 160.97 ft.
The height of the building is sin 52=height/160.97
so height is 126.85 or 127 feet.
