In the diagram ab is a straight road and c indicate the bottom of a vertical clif in the same vertical plane as ab the angle of elevation to the top of the from a is 24 degres and from b 300m closer to the clif the angle ofg elevation is 38 degres.calculate the height of the clif
note that if the height is h,
h*cot24° - h*cot38° = 300
Now just find h.
