Answer 1

Answer:

Given:

<1 = 40 degrees.

Therefore, <3 = 40 degrees. (Vertically Opposite Angles)

Now, <1 + <4 = 180 degrees. (Linear Pair)

40 + <4 = 180.

<4 = 180 - 40 = 140 degrees.

Now <4 = <2 (Vertically opposite Angles)

Therefore, <2 = 140 degrees.

Also, <2 = <6, <1 = <5 (Corresponding Angles)

Therefore, <6 = 140 degrees, <5 = 40 degrees.

Now <5 = <7 and <6 = <8 (Vertically Opposite Angles)

Therefore, <7 = 40 degrees, <8 = 140 degrees.

Answer 2

Step-by-step explanation:

Angle 1= angle 3 (vertically opp.)

1=5(corresponding)

1=7(alternate)

2=180-angle1 =140(Linear pair)

2=4(vertically opp.)

2=6(corresponding)

2=8(alternate)

Hence 1,3,5,7 = 40 degree

2,4,6,8=140 degree
