34 A sign 46 feet high is placed on top of an office building. From a point
on the sidewalk level with the base of the building, the angle of
elevation to the top of the sign and the angle of elevation to the bottom
of the sign are 40° and 32°, respectively. Sketch a diagram to represent
the building, the sign, and the two angles, and find the height of the
building to the nearest foot.
