Question

) Ratio of two angles of a linear pair is 2:1 , find the angles.​

Answer 1

120° and 60°

let the angles be x

then ,

2x+x=180

3x=180

x=60

2x=2×60=120°

x=60=60°

Answer 2

Answer:

LET FIRST ANGLE BE 2x

let second angle be x

2x + x = 180° ( linear pair)

3x = 180°

x = 180°/3

x = 60°

hence,

first angle = 2x = 2×60° = 120°

second angle = x = 60°
