4.8 Applications and Models b = 19.4 AC B a c Solve the right triangle. B = ?= 90 – 34.2 = a = 13.18

If the ladder is 40’ long and the angle of elevation is 42, how high up is the fireman? 40’ h

At a point 200 feet from the base of a building, the angle of elevation to the bottom of a smokestack is, while the angle to the top is. Find the height, s, of the smokestack alone. 200 ft. s x 265.41 -140.04 125.37 ft.

Trigonometry and Bearings N S W E N S W E

A ship leaves port at noon and heads due west at 20 knots (nautical miles per hour). At 2 P.M., to avoid a storm, the ship changes course to N W. Find the ship’s bearing and distance from the port of departure at 3 P.M.. A B D 2(20) = 40 nm 20 nm c d b = 16.18 =11.76 Now find angle A. Find c. c = 57.4 nm
