Two angles form a linear pair. The measure of one angle is 1/3 the measure of the other

Question

I didn’t really understand the problem and how I’m supposed to do it.

Answer 1

From the Internet:

A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so alinear pair of angles must add up to 180 degrees

So, x + y = 180

x = 1/3(y)

1/3(y) + y = 180

4/3(y) = 180

y = 135
