The answer is (B) 2<em>k</em><em> </em>= 18
Answer:
"There are 30 chairs in 5 rows. How many chairs are in each row?" Would be the correct story problem.
Angle BOC = 120
PROOF
Angle A + Angle B + Angle C = 180
So, Angle B + Angle C = 120 (Angle A = 60)
Now 1/2 (Angle B + Angle C) = 60
1/2 Angle B + 1/2 Angle C = 60..............i
In triangle BOC
1/2 Angle B + 1/2 Angle C + Angle BOC =180
(BO and CO are angle bisectors)
Or 60 + Angle BOC = 180 (using i)
OR ANGLE BOC = 120
