From the top of a cliff 32 meter high it is noted that the angles of depression of two boats lying in the line due east of the cliff are 21 degrees and 17 degrees How far are the boats apart?

Angle of depression equals angle of elevation (alternate angles)
So use the tangent ratio to find the distance of the two ships are from the base of the cliff:
104.6672838 - 83.36285007 = 21.30443373 meters apart.

What is the distance between two boats that are in a straight line from the base of a vertical cliff that is 36m high and their angles of depression are 17 degrees and 25 degrees respectively?
Use trigonometry to find the distance of each boat from the cliff's base and subtracting both distances gives a distance of 40.5 meters between them to 1 d.p.
