From a boat on the lake, the angle of elevation to the top of a cliff is

17°37\'.

If the base of the cliff is

968

feet from the boat, how high is the cliff (to the nearest foot)?

Solution

tan = opp/adj
17°37 = 17 + 37/60 = 17.62°, radians = (17.62°/180°)pi = 0.308 radians
968 *tan(0.308 radians) = 307.44 ft
