A boy is 1.5 m tall standing 12 m away from a church building which has a tower on top of its roof. The top of the cross on the tower is 14.6 m away from the boy's head (eyes). If the boy has to raise his eyes through an angle of 31° in order to see the top of the roof, calculate: a) the angle through which the boy must raise his eye to see the top of the cross on the tower, correct to the nearest degree. b) the height of the top of the cross from the ground, correct to one decimal place. c) the height of the church building, correct to one decimal plaçe.
