Solve the triangle. Round lengths to the nearest tenth and angle measures to the nearest degree. B = 15° C = 113° b = 49A = 50°, a = 174.3, c = 149.2A = 52°, a = 151.2, c = 176.3A = 52°, a = 149.2, c = 174.3A = 50°, a = 176.3, c = 151.2
Accepted Solution
A:
Answer: A = 52°, a = 149.2, c = 174.3Step-by-step explanation:Technology is useful for this. Many graphing calculators can solve triangles for you. The attachment shows a phone app that does this, too.___The Law of Sines can give you the value of c, so you can choose the correct answer from those offered. c = sin(C)·b/sin(B) = sin(113°)·49/sin(15°) ≈ 174.271 ≈ 174.3 . . . . . third choice
