Question 8-10

Two sides and an angle are given. Determine whether the given information results in one triangle, two triangles, or no triangle at all. Solve any triangle(s) that results. 8) B = 410, a = 4, b = 3 8) A) one triangle B) two triangles A = 290, C = 1109, c = 5.7 A1 = 610, C1 = 78, c1 = 0.1; A2 = 119, C2 = 20, C2 = 0.1 C) two triangles D) no triangle A1 = 610, C1 = 780, c1 = 4.5; A2 = 1190, C2 = 20, C2 = 1.6 Solve the triangle. 9) b = 7, c = 10, A = 1120 9 A) a = 14.2, B = 270, C = 410 B) a = 20, B = 25, C = 43 C) a = 17.1, B = 290, C = 390 D) no triangle Solve the problem. 10) A plane takes off from an airport on the bearing $29W. It continues for 20 minutes then changes to 10) bearing $52W and flies for 2 hours 20 minutes on this course then lands at a second airport. If the plane's speed is 420 mph, how far from the first airport is the second airport? Round your answer correct to the nearest mile. A) 1010 mi B) 1011 mi C) 1110 mi D) 1111 mi
