Question

Given that ∠A and ∠B are linear pairs, if m∠A = 112° then what is m∠B?

If m∠2 = 25° and m∠3 = 3x + 5 , then...

A) x = 25 B) x = 50 C) x = 40 D) x = 100

Answerr plzz

Answer 1

B)x=50

Explanation:

it is a linear pair so it equals 180

180=25+3x+5

180=30+3x

-30 -30

150=3x

÷3 ÷3

50=x
