Answer 1

60,140

Explanation:

alternate interior angles are congruent. and then 1 and 4 are supplementary angles which create 180

Answer 2

Angle 2 is 60. Find angle 8

solution,

2=8(being co-alternate angle)

60=8

so, 8=60,,

If Angle 4 is 40 degrees. Find Angle 1

solution,

again,

let 1 be x

4+x=180

40°+x=180

x=180-40

x=140,,

therefore x=140,,
