Question

When lines l and m intersect at a point O,the ratio of the measure of adjacent angles so formed is 3:1. Find the measure of all the four angles.​

Answer 1

Well, the angles are always supplementary, i.e., the sum of the two is always 180°.

Since the angles are in the ratio 3:1, let them be 3x and x.

We have,

3x + x = 180°

4x = 180°

x = 45°

3x = 135°

Answer 2

Answer:

3x + x = 180

4x = 180

x = 45

3x = 135
