Question

observer 1.5meters tall is 20.5 metres away from a tower 22 mts high determine the angle of elevation of the top of the tower from the eye of the observer

Answer 1

the distance between observer and tower is 20.5
the height of the observer is 1.5
the height of the tower is 22
the angle of elevation from the observer to top of the tower is ?
tower height- observer height
22-1.5=20.5
it forms a right triangle
tan theta = opposite side/adjesent side
than theta=20.5/20/5=1
where the theta=45°
the angle of elevation from the observer to top of the tower is 45°
