1. In , j = 10, k = 7, and = 5. What is to the nearest tenth? A. 139.5 B. 111.8 C. 40.5 D. 27.7 Hint 2. In , n = 8, m = 16, and = 32. Find to the nearest tenth. A. 24.7 B. 132.6 C. 15.4 D. 123.3 Hint 3. In FAD, a = 12, d = 15, and mF = 63. Find the value of f to the nearest tenth. A. 15.6 B. 23.1 C. 14.3 D. 9.1 Hint 4. Raul lives in Middleburg. He wants to find the distance between Easton and Westerville. He knows that Easton is 5.7 miles from Middleburg, that Westerville is 9.3 miles from Middleburg, and that the angle formed by the two lines (from Middleburg to Westerville and from Middleburg to Easton) is 69.4°. To the nearest tenth of a mile, what answer should Raul come up with? A. 4.1 miles B. 12.5 miles C. 9 miles D. 9.6 miles Hint 5. Mike and Veronica are camping, and they have decided to build a small tower at their campsite, using just ropes and wooden poles. One of the poles is 11 feet long, and they want to anchor it into the ground with a rope. One end of the rope will be attached to the top of the pole, and the other end will be anchored in the ground in a spot 15 feet from the base of the pole. If they want the pole to lean away from the anchor at an 80° angle with the ground, how far will the rope have to reach, to the nearest tenth of a foot? A. 20.1 feet B. 12.7 feet C. 17 feet D. 22.5 feet Hint
