Please Solve each triangle using the law of Sines or law of Cosines. Round sides to the nearest hundredth and angles to the nearest tenth.

Solution

6. A = 50 \' C = 20

a = 12 ;

use sine rule: to find side c:

c/sinC = a/sina

c = sinC*a/sinA =sin20*12/sin50 = 5.36

B = 180 -B -C = 180 -50 -20 = 110 deg

b/sinB = a/sinA

b = sinB*a/sinA = sin110*12/sin50 = 14.72
