Question

Two angles of a linear pair are in the ratio 2:7.Find the angles.

Answer 1

Step-by-step explanation:

Two angles of linear pair are in the ratio 2:7

so,let angles be 2x and 7x

we know that sum of two angles of a linear pair =180°

therefore,2x+7x=180°

9x=180°

x=180/9

x=20°

so, angles are 2×20=40° and 7×20=140°
