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 44. From the same position, the students measure the angle of depression of the base of the taller building. The angle is 53. The students then measure the horizontal distance between the two buildings. The distance(ED) is 18.0 m. The students drew this diagram. To the nearest ten, how tall is each building?Required to answer. Single choice.
