Question

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

Answer 1

Step-by-step explanation:

the sum of the angles of a linear pair is equal to 180 degrees.

let x represent one of the angles.

let y represent the other of the angles.

you get x + y = 180

since the ratio of one of the angles to the other is 2:1, then you get:

y = 2x which makes y the angle that has a 2:1 ratio to x.

substitute for y in the equation of x + y = 180 to get:

x + 2x = 180

combine like terms to get:

3x = 180

divide both sides of the equation by 3 to getr:

x = 60 degrees.

that makes y = 2x = 120 degrees.

the 2 angles are 60 degrees and 120 degrees

Answer 2

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 = 2×60= 120°

x = 60°
