2. Write Sin(tan'1(:r:)) as an algebraic expression in terms of 53. 3. Use the Law of Sines to solve for all possible triangles that satisfy the given conditions. m, you must draw a triangle and ll in the given conditions. A. a : 20, b : 45, and mZA : 1250 B. a : 75, b : 100, and mZA : 300 4. Solve triangle ABC-1m. You must draw a picture of the triangle. If two triangles are possible, you must solve both. A. b = 30, c = 60, and mZA = 70 B.a=20, b=25, and c=22
