If two angles form a linear pair and the measure of the first angle is one-fifth the measure of the second angle, what is the measure of each angle?

Well, one angle has one share of the linear angle, and the other one has five shares. All together, they add up to six shares of the linear angle.

BUT ... a linear angle adds up to 180°. So each share must be (180°/6) = 30°.

The smaller one (one share) is 30°, and the larger one (5 shares) is 150°.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
