A tower is standing on a horizontal ground. To calculate the height of the tower, a surveyor at A, due east of the tower, measures the angle of elevation of the top of the tower and found it to be 28.4 degrees. He then moves to point B, directly south of A, and measures the angle of elevation of the top of the tower and found it to be 23.6 degrees. Point B is 72.8 m from A. Calculate the height of the tower. Select one: O a. 53.94 m O b. 41.88 m O c. 66.97 m O d. 59.76 m
