1. Sketch each triangle. Use the Law of Sines to solve for all possible triangles that satisfy the given conditions. (a) LA = 30, LC = 65, b = 10 (b) a = 28, b= 15, LA = 110 (c) a = 20, c = 45, LA = 1250 (d) b = 25, c = 30, LB = 25 2. For the triangle shown, find the length AD. C 250 12 250 B 12 D A 3. A pilot is flying over a straight highway. He determines the angle of depression to two posts, 5 mi apart, to be 320 and 48, as shown in the figure. 320 5 mi (a) Find the distance of the plane from point A. (b) Find the elevation of the plane (the distance from the ground). 4. Solve triangle ABC given the following information. (In other words, find the missing side lengths and angles.) (a) LA = 46.50, b = 10.5, and c = 18 (b) a = 20, b = 25, c = 22 5. Two straight roads diverge at an angle of 65. Two cars leave the inter- section at 2:00 P.M., one traveling at 50mi/h and the other at 30 mi/h. How far apart are the cars at 2:30 P.M
