Rule : Sum of angles in a straight line is 180°

We can say that 2x + 3x = 180°
5x = 180° => x = 36°

Again using the same property that in the other straight line
3x + y + 30 = 180°
3*36° + y + 30 = 180°
y = 180 - 108 - 30 = 42°(Option E)

We can first solve for x. Since 2x and 3x make a straight line:

2x + 3x = 180

5x = 180

x = 36

We also see that 2x = y + 30; thus:

2(36) = y + 30

72 = y + 30

42 = y
