Question

two angles of a linear pair are in the ratio of 2ratio7. find the angles.

Answer 1

Hey your answer here,
Let yo be x angle
2x+7x=180. {linear pair,)
=}9x=180
=}x=180/9
=}x=20

so we find each angles
=}2x=2*20=40
and 7x=7*20=140

Answer 2

let the angles be 2x,7x
linear pair =180
2x+7x=180
9x=180
x=180/9
x=20
2x=2×20
2x=40
7x=7×20
7x=140


the required angles are 40 and 140 :)
