Question

If m<1= w+5 and m<2=3w +7 if <1 and <2 form a linear pair what is the value

Answer 1

Answer:

w = 42

Step-by-step explanation:

A linear pair is a pair of adjacent angles which add up to 180 degrees(supplimentary).

Given m<1 = w + 5, m<2 = 3w + 7, and the fact that m<1, and m<2 form a linear pair. This relationship can be given by:

m<1 + m<2 = 180.

To solve just substitute the expressions given by the angles, and solve.

m<1 + m<2 = 180

(w+5)+(3w+7) = 180 →

4w + 12 = 180
