Two midshipmen want to determine the heights of two buildings. They stand on the roof of the shorter building. The students use a clinometer to measure the angle of elevation of the top of the taller building. The angle is 44°. From the same position, the midshipmen measure the angle of depression of the base of the taller building. The angle is 53°. The midshipmen then measure the horizontal distance between the two buildings. The distance is 18.0 m. The students drew this diagram. B 44° 53° 18.0 m

Question

Determine the height of the taller and shorter building.

Two midshipmen want to determine the heights of two buildings. They stand on the roof of the
shorter building. The students use a clinometer to measure the angle of elevation of the top of
the taller building. The angle is 44°. From the same position, the midshipmen measure the
angle of depression of the base of the taller building. The angle is 53°. The midshipmen then
measure the horizontal distance between the two buildings. The distance is 18.0 m. The
students drew this diagram.
