Angle of Elevation

Use this diagram to answer the question below. *Hint: use the adjustable diagram to help!

A cable of length 45 metres is anchored from the ground to the top of a communications mast. The angle of elevation of the cable to the top of the mast is 60°. [br]Find the height of the communications mast, to the nearest metre.[br]

37m 59m 39m 25m

What ratio did you use to solve the question above?
