The figure shows a shot-put ring. The shot is tossed from A and lands at B. Using modern electronic equipment, the distance of the toss can be measured without the use of measuring tapes. When the shot lands at B an electronic transmitter placed at B 5.40 sends a signal to a device in the official's booth above the track. 525 feet The device determines the angles at B and C. At a track meet, 8430 the distance from the official's booth to the shot-put ring is 525 feet. If B =84.3" and C =5.4", determine the length of the toss to the nearest tenth of a foot. C B The toss was about feet. Round to the nearest tenth as needed.)Solve the triangle. b =6 1=4 Round all angles to the nearest degree. A B C=6 (Do not round until the final answer. Then round to the nearest degree as needed.) (Do not round until the final answer. Then round to the nearest degree as needed.) (Do not round until the final answer. Then round to the nearest degree as needed.)Use Heron's formula to find the area of the triangle. Round to the nearest square foot. Side a =7 feet Side b =7 feet Side c =2 feet The area is approximately square feet
