Question

A transversal intersects two parallel lines such that the ratio between the interior angles on one of its side is 7 : 5, then the measure of the smaller angle is​

Answer 1

Step-by-step explanation:

Interior angles are supplementary i.e. they add up to 180 degrees

So 180 degrees is divided into (3 + 7) = 10 parts

Each part is 180/10 = 18 degrees

3 parts, smaller angle = 3 x 18 = 54 degrees
