Question

In the given figurel||m and t is a transversal . If angle1and angle2 are in the ratio 5:7,find the measure of each of the angles angle1,angle2,angle3 and angle 8

Answer 1

as per the figure,

angle1+angle2=180

5x+7x=180

12x=180

x=180/12

x=15

therefore, two angles are 75,105

angle3=angle1 (vertically opposite angles)

angle2=75

angle8=angle1

angle8=75 (alternate exterior angles)

Answer 2

Answer:

as per the figure,

angle1+angle2=180

5x+7x=180
