ang = 25°
hyp = ?
adj = 67
opp = ? <-- figure this out

Draw a right triangle with one of the sides as the height of the building then make the angle between that side and the hypotenuse equal to the angle of depression. Then you need to use trig to solve for the other side, I suggest using the tangent function.
