Question

two angles are making a linear pain.If one of them is one-third of the other them find the angle

Answer 1

Step-by-step explanation:

Let one angle be x.

It is given that other angle is one-third of first.

So, other angle will be x/3.

Again, given that both the angles are making a linear pair.

So, their sum will be 180°

x + x/3 = 180°

(3x + x)/3 = 180°

4x/3 = 180°

x = (180° x 3)/4

x = 135°

Hence, the angles are 135° and 1/3 x 135°, i.e. 135° and 45°.

Answer 2

Answer:

135° and 45°

Step-by-step explanation:

Given:-

Two angles are making a linear pain.If one of them is one-third of the other them

To Find:

The two angles

Solution:-

Let first angle be x⁰

second angle=x/3⁰

As we know that of the two angles are making linear pair so they are making an angle of 180⁰

So,

x+x/3=180

3x+x=180×3

4x=180×3

x=180×3/4=135

1st angle=x=135°

2nd angle=x/3=135/3=45°
