a To estimate the height of a mountain, two students find the angle of elevation from a point (at ground level) b = 560 meters from the base of the mountain to the top of the mountain is B - 45. The students then walk a = 2950 meters straight back and measure the angle of elevation to now be o = 32". If we assume that the ground is level, use this information to estimate the height of the mountain. The height of the mountain is meters.Question 9 Along a long, straight stretch of mountain road with a 6.9 % grade, you see a tall tree standing perfectly plumb alongside the road.' From a point 510 feet downhill from the tree, the angle of inclination from the road to the top of the tree is 6.4 0 . Use the Law of Sines to find the height of the tree to the nearest tenth of a foot. (Hint: First show that the tree makes a 93.9 % angle with the road.) feet The word "plumb" here means that the tree is perpendicular to the horizontal.In order to estimate the height of a building, two students stand at a certain distance from the building at street level. From this point, they find the angle of elevation from the street to the top of the building to be 41 . They the move 300 feet closer to the building and find the angle of elevation to be 48 . Assume that the street is level, estimate the height of the building to the nearest foot. feet
