Question

if measure of angle 1 and measure of angle 2 form a linear pair and measure of angle 1 is 18 degrees less than five times the measure of angle 2 what if the measure of angle 1

Answer 1

A linear pair is a pair of adjacent angles formed when two lines intersect. 

Linear pair angles add up to 180 degrees because they lie on a straight line. 

Let x = smaller angle 

Let 5x - 18 = bigger angle 
x + 5x -18 = 180
6x = 198
x = 198/6 
x = 33
The smaller angle is 33 degrees and the bigger is 147 degrees
