4 Given a 82 b 37 and c 108 solve the triangle Find the an

4. Given a 8.2, b = 3.7, and c = 10.8, solve the triangle. Find the angles to the nearest tenth

a = 8.2 , b = 3.7 , c = 10.8

applying law of cosines

10.8^2 = 8.2^2 + 3.7^2 - 2 (8.2)(3.7) cos C

C = 126.1 degrees

3.7^2 = 8.2^2 + 10.8^2 - 2 (8.2) (3.7) cos A

A = 37.9 degrees

B = 180 - (126.1 + 37.9)

B = 16.1 degrees
