Question

8 In a triangle ABC, angleA = 120° and angle
B = 2ZC. Find angleB and AngleC.​

Answer 1

Answer:B=40°,C=20°

Step-by-step explanation:

I think the question is.... In a triangle ABC, angle A = 120° and angle

B = 2*C. Find angle B and Angle C.​

Answer-

We know that the sum of the angles of a triangle is equal to 180°.

∠A+∠B+∠C=180°

or,120°+2C+C=180°

or,3C=180°-120°=60°

or,C=60°/3=20°

Now, B=2*C=2*20°=40°
