The angle of elevation of the top of a tower to point A on the ground is 61 degrees. At point B it is 600 feet farther from the base, in line with the base and the first point and in the same plane, the angle of elevation is 32 degrees. Find the height of the tower.

This problem is tricky because I don't know the distance point A is from the base. Point B would be a distance of 600ft.+ the distance of point A, I think.

heigth=A*tan61

height=B*tan32

where A and B are the distances from the tower. B-A=600 or B=600+A

subtract equation 2 from 1

height-height=0=Atan61-(600+A)tan32

solve for A

then, solve for height.
