Use the Law of Sines to find the missing angle of the triangle. Find m B given that c = 83, a = 44, and m A = 31 A. 76 3 degree B. 15.8 degree C. 0.72.7 degree D. 164.2 degree

Solution

Law sines states that the ratio of side to angle opposite that side are equal

So, 44/sin31 = 83/sinb

= sin-1(83*.515/44)

= sin-1(.97)

= 75.9
