Question
From a point on the ground, the angle of elevation to
the top of a building is 30 degrees. If the distance between the point and the base of the building is 50 meters, find the height of the building (use β3 = 1.732).Solution
Let the height of the building be h. Using tan 30 degrees = h/50 and tan 30 degrees = 1/β3 = 1/1.732, h = 50 * (1/β3) = 50 * 0.577 = 28.87 m. Correct Answer: b) 28.87 m
