solve triangle ABC given that A=56 B=57 b=9 a) C=64, a=10.2, c=9.8 b) C=67, a=10.2, c=9.88 c) C=67, a=8.9, c=9.88 d) C=66, a=8.7, c=9.88
i think its b or c
Solve for the missing angle first A+B+C=180° C=180°-A-B
Then use the fact that the largest side of a triangle is opposite to the largest angle
yea that equals 67 b or c
good, so which angle is the largest?
is it answer b?? @unkleRhaukus
