Question

There are two parallel lines l and m are cut by a transfesal .If angle5 and angle 6 are in the ratio 5:7 Find the measure of angle1,2,3,4,7,8​

Answer 1

Step-by-step explanation:

5x+7x=180

X=180/12

X=15

so

5*15=75

7*15=105

1=75(corresponding angles)

4=75(vertically opposite angles)

8=75(vertically opposite angles)

and angles 2=105(linear pair)

3=105(vertically opposite angle)

6=105(vertically opposite angle)
