http://www methL(om\'Student MATH 112 Plane Trigonometry Fall 2017 Test: Test 4 This Question: 1 pt 90f 1s(7 complete) | The figure shows a 1250-yard-long sand beach and an ol platlorm in the ocean. The angle made with the platform from one end of the beach is 82 and from the other end is 76\" Find the distance of the oil platform, to the nearest tenth of a yard, from each end of the beach 1250 yards The platform is aboutyards torn one end of the beach andyards from the other (Use descending order. Round to the nearest tenth as needed ) Enter your answer in each of the answer boxes

Solution

let the two distances are d and e

then dsin82 = esin76

and dcos82 + ecos76 = 1250

=> dcos82 + (dsin82/sin76)cos76 = 1250 => d = 3237.7157 yard

=> e = 3304.3601 yard
