angle of depression = angle looking up cliff from level at canoe
tan 70 = 15 / near distance
near distance = 5.46
tan 57 = 15/ far distance
far distance = 9.74
distance between= 9.74 - 5.46
Angles of depression of two canoes are 57degree and 70degree from the top of a vertical cliff, the foot of which is on the same straight line as the two canoes (A and B). if the cliff is 15m high. calculate the distance between the 2 canoes
