Problem 33

The terminal side of \(\boldsymbol{\theta}\) lies on the given line in the specified quadrant. Find the values of the six trigonometric functions of \(\boldsymbol{\theta}\) by finding a point on the line. y=-x, II

Problem 34

Find (if possible) the complement and supplement of each angle. (a) 3 (b) 1.5

Problem 35

An airplane flying at 600 miles per hour has a bearing of \(52^{\circ}\). After flying for 1.5 hours, how far north and how far east will the plane have traveled from its point of departure?

Problem 37

A ship leaves port at noon and has a bearing of \(\mathrm{S} 29^{\circ} \mathrm{W}\). The ship sails at \(20 \mathrm{knots}\). (a) How many nautical miles south and how many nautical miles west will the ship have traveled by 6: 00 P.M.? (b) At 6: 00 P.M., the ship changes course to due west. Find the ship's bearing and distance from the port of departure at 7:00 P.M.

Problem 39
