Answer:
72.65m (2dp) is the height of the cliff
Step-by-step explanation:
The height of the cliff can be calculated using trigonometry
Since we know the angle of elevation and the adjacent = side of the angle, and we are looking for the opposite side of the angle, which say is h, we will use tan since we are not dealing with the hypotenuse
tan(36) = h/100
100tan(36) = h
h = 72.65m (2dp)
