Question

In triangle ABC, the measure of the angles are 2x, x, and 3x respectively. What is the measure of angle B?

Answer 1

Answer:

Step-by-step explanation:

2x, x, and 3x all have to add up to equal 180 by the Triangle Angle-Sum Theorem.

2x + x + 3x = 180 and

6x = 180 so

x = 30

Therefore, angle B is 30.
