Question

two angles are in the ratio 3:2,if they are linear pair find them​

Answer 1

Answer:

108° & 72° respectively..

Step-by-step explanation:

Sum of angles forming a linear pair = 180°

Let both the angles be 3x and 2x.

So, the equation so formed is:::

3x+2x=180°

5x=180°

x=36°

So,

1st angle = 3x = 3×36 = 108°

2nd angle = 2x = 2×36 = 72°

Answer 2

SOLUTION

GIVEN

• Two angles are in the ratio 3 : 2

• They are linear pair

TO DETERMINE

The angles

EVALUATION

Here it is given that the two angles are in the ratio 3 : 2

Let the angles are 3x and 2x

Now the angles are in linear pair

We know that linear pair of angles are formed when two lines intersect.

Thus sum of the linear pair angles = 180°

So by the given condition

3x + 2x = 180°

⇒ 5x = 180°

⇒ x = 36°

First angle = 3 × 36° = 108°

Second angle = 2 × 36° = 72°

FINAL ANSWER

Hence the required angles are 108° , 72°
