Question

The measures of the angles in a linear pair are x° and
(x +30°). Find the measure of each of them.​

Answer 1

X+x+30=180

2x+30=180

2x=180-30

2x=150

x=150/2

x=75

x+30=75+30

=105

$105+75=180$

Answer 2

x + ( x+ 30 ) = 180 ( linear pair)

2x = 180 - 30

x = 150/2

x= 75

angle 1 = 75

angle 2 = 75 + 30 = 105
