Question

In figure 5, AB parallel to CD and PQ is the transversal . If angle 1:angle 2 is equal to 3 : 2 find the measure of all the angle from 1 to 8.​

Answer 1

Answer:

1 and 2 angle ratio 3:2

1 angle value is 3/5* 180=108

2 angle value is 180-108=72

3 =108

4=72

5=108

6=72

7=108

8=72

Answer 2

Answer:

Let the angle 1 = 3x

And angle 2 = 2x

Then by using linear pair angle property

$3x + 2x = 180$

$= > 5x = 180$

$= > x = 180 \div 5 = 36$

Then

Angle

1 = 3 * 36 =108

2 = 2 * 36 = 72

Angle 1 = angle 3 = angle 5 = angle 7 = 108 degree

Angle 2 = angle 4 = angle 6 = angle 8 = 72 degree
