Question

. Solve the triangle. A = 32°, a = 19, b = 12 B = 19.6°, C = 148.4°, c ≈22.5 B = 19.6°, C = 128.4°, c ≈28.1 Cannot be solved B = 19.6°, C = 128.4°, c ≈16.9

Answer 1

Explanation:

sin(32)/19 = sin(B)/12

cross multiply

12 sin(32) = 19 sin(B)

sin(B) = 12 sin(32) /19 = 0.334686

B = sin°-1(0.334686)

B = 0.321272 radian

B = (0.321272)*180/pi degrees = 19.55°

C = 180-32-19.55 = 128.45°

sin(32)/19 = sin(128.45)/ c

cross multiply

c sin(32) = 19 sin(128.45)

c = 19 sin(128.45) /sin(32) =28.08....
