ANGEL OF DEPRESSION

Question

A lighthouse, depression 30 of m a tall, ship is from built the on top top of of Q the cliff that lighthouse is 180 m high. Find the angle the bottom of the cliff.

Answer 1

not sure I understand the question

but construct a right triangle, 2 sides = 30 and 180

hypotenuse = sqr(30^2 + 180^2)

tan^-1(6) = the angle or maybe 90 - the angle depending on

where the angle of depression is, given the context of the problem
