    Trig triangle problem

    This should be an easy problem but I don't know what they are trying to convey.

    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.
