Two students 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 44o . From the same position, the students measure the angle of depression of the base of the taller building. The angle is 53o . The students then measure the horizontal distance between the two buildings. The distance is 18.0 m. The students drew this diagram. How tall is the tallest building?
