Include diagrams and units in your solutions. 1. An overhead crane is suspended from a ceiling by two chains. One chain is 4.6 m long and forms an angle of 60 with the ceiling. The other chain is 6.4 m long. What angle does the larger chain make with the ceiling? 2. At noon, two tracking stations on Earth, 20 km apart, measure the angles of elevation of a rocket that was launched with a weather satellite. From Station A, the angle of elevation is 41 and from Station B it is 750. Find the altitude of the rocket to the nearest tenth. Note: Both tracking stations are on the same side of the rocket. 3. A farmer has a field in the shape of a triangle. The farmer has asked the manufacturing class at your school to build a metal fence for his farm. From one vertex, it is 435 m to the second vertex and 656 m to the third vertex. The angle between the lines of sight to the second and third vertices is 49. Calculate how much fencing he would need to enclose his entire field. 4. A balloonist at an altitude of 226 m observes the angles of depression of one point on the ground as 2, and of another point as 3. The horizontal angle between the lines of sight to the two points is so. What is the distance between the two points? Click on the Submit Your Work link below to access the rubric for this activity.
