Question

7. At a point on the ground 20 m from the wall of a house, the elevation of the bottom of the window was 12°. From the same point, the elevation of the top of the window was 14°. Calculate the height of the window.​

Answer 1

d = h(cot1 - cot2)

d = 100(cot30 - cot45))

d = 100* (1.732 - 1)

d = 100*0.732

d = 73.2 m
