Question

From the top of a building 120m high, the angle of depression of two cars on the ground in line with the base of the building are 18' and 65' respectively. Calculate the distance between the cars.

Answer 1

Do you really mean 18 minutes and 65 minutes or do you mean degrees?

Answer 2

A1 = 90 - 18 whatever
A2 = 90 - 65 whatever

d1 = 120 tan A1
d2 = 120 tan A2

what is d1 - d2 ?
