Question

ratio of two angles of a linear pair is 2:1 . find its angles

Answer 1

Answer:

120° and 60°

Step-by-step explanation:

let the common ratio be x

So,

2x + 1x = 180° (linear pair = 180°)

Then,

3x =180°

x=180°/3

x=60°

the angles are

2x = 2 x 60 = 120°

1x = 1 x 60 = 60°

Answer 2

Answer:

let the angles = 2x and 1x

so according to the question

  2x +1x=180 degree  (linear pair)

3x = 180 degree

x=60 degree answer

measure of  first angle = 120 degree

measure of 2nd angle = 180 -120 degree = 60 degree answer
