- For Exercises 49 to 50, use the following information. Relative to its point departure or some other point of reference, the angle that is used to locate the position of a ship or airplane is called its bearing. The bearing may also be used to describe the direction in which the airplane or ship is moving. By using an angle between 0 and 90, a bearing is measured from the North-South line toward the East or West. In the diagram, airplane A which is 250 miles from Chicagos O Hare airports control tower has a bearing of S 53 W. Find bearing of airplane C relative to the control tower.arrow_forwardIn Exercises 39 to 45, angle measures should be given to the nearest degree; distance should be given to the nearest tenth of a unit. While a helicopter hovers 1000 ft above the water, its pilot spies a man in a lifeboat through an angle of depression of 28. Along a straight line, a rescue boat can also be seen through an angle depression of 14. How far is the rescue boat from the lifeboat?arrow_forwardIn Exercises 27 to 34, use the drawings, where provided, to solve each problem. Angle measures should be given to the nearest degree; distances should be given to the nearest tenth of a unit. An airplane flying at the rate of 350 feet per second begins to climb at an angle of 10. What is the increase in altitude over the next 15 seconds?arrow_forward
- Refer to the following figure in answering Exercises 7 through 13. It may be helpful to sketch figures. When 1 is slightly greater than 0: a. How does side y compare to side r? b. How does side x compare to side r? c. How does side x compare to side y?arrow_forwardIn Exercises 39 to 45, angle measures should be given to the nearest degree; distance should be given to the nearest tenth of a unit. From atop a 200-ft lookout tower, a fire is spotted due north through an angle of depression of 12. Firefighters located 1000 ft due east of the tower must work their way through heavy foliage to the fire. By their compasses, through what angle measured from the north toward the west must the firefighters travel?arrow_forwardFor Exercises 1 through 6, compute angles to the nearer minute or hundredth degree. Three views of the angular portion of a tool are shown. Compute C.arrow_forward
- Refer to the following figure in answering Exercises 7 through 13. It may be helpful to sketch figures. When 1 is 0: a. What is the value of side y? b. How does side x compare to side r?arrow_forwardFor Exercises 35 to 38, make drawings as needed. In a right circular cone, the slant height is 13cm and the height is 10cm. To the nearest degree, find the measure of the angle that is formed by the radius and slant height.arrow_forwardIn Exercises 21 to 30, use the drawings, where provided, to solve each problem, Angle measures should be found to the nearest degree; lengths should be found to the nearest tenth of a unit. The basket of a hot-air balloon is 300 ft high. The pilot of the balloon observes a stadium 2200 ft away. What is the measure of the angle of depression?arrow_forward
- In Exercises 27 to 34, use the drawings, where provided, to solve each problem. Angle measures should be given to the nearest degree; distances should be given to the nearest tenth of a unit. A 12-ft rope secures a rowboat to a pier that is 4ft above the water. Assume that the lower end of the rope is at water level. What is the angle formed by the rope and the water? Assume that the rope is taut.arrow_forwardIn Exercises 5 to 8, describe in one word the relationship between the angles. ABD and DBCarrow_forwardFor Exercises 1 to 8, use the figure provided.
