A 6ft tall observer is standing at the top of a cliff. He spots a house in the adjacent valley at an angle of depression of 12 degrees. The cliff is 54 ft tall

How far away is the house from the base of the cliff?

Height = 54=6 = 60 ft

Tan = opp/ adj = 60/distance

tan 12 = 60 / distance

60 / ( tan(12^{o}) = distance Finish from here !
