Trigonometry

Find the magnitude and direction angle (to the nearest tenth) for each vector. Give the measure of the direction angle as an angle in [0,360°]. (√2,-1> Which one is the correct answer? √3; 305.3 3; 324.7 √3; 324.7 3; 125.3

Trigonometry

Solve the problem. Starting at point A, a ship sails 24 km on a bearing of 211°, then turns and sails 33 km on a bearing of 302°. Find the distance of the ship from point A. Which is the correct answer? 57 km 73 km 16 km 40 km

Trigonometry

Solve the problem. A plane flying a straight course observes a mountain at a bearing of 35.3° to the right of its course. At that time the plane is 9 km from the mountain. A short time later, the bearing to the mountain becomes 45.3°. How far is the plane from the mountain when the second bearing is taken (to the nearest tenth of a km)? Which is the correct answer? 11.1 km 4.9 km 12.2 km 7.3 km
