Question

In △ABC , m∠A=x° , m∠B=(3x+30)° , and m∠C=2x° . What is the measure of ∠B ?

Answer 1

Answer: 105

Step-by-step explanation:

Angle A, B, and C all add up to 180 degrees. So you combine the equations and get “6x+30=180” so x=25 and then you plug 25 for x into the equation for angle B and you get “75+30” which equals “105”.
