Hope this helps :)

Answer 2

Step-by-step explanation:

1.a. 180-39=141

1.b. 90-47 =43

1.c. 180-157=23

1.d. 90-39=51

2.a. 88-58=30

2.b. 125-36=89

2.c. 98-64=34

2.d. 86-62=24

3.a. Angle A=180-119=61 & angleB=180-61=119

3.b. AngleA=180-146=34 & angleB =180-34=146

3.c. AngleA =180-35=145 & abgleB=180-35=145

3.d. AngleA = 180-111=69 & angleB=180-111=69

For question 3, opposite angles are congruent which they are equal can be used.

4. Answer is b i.e. 2

5. Answer is d i.e. 180°

Linear pair of angles is formed when two lines intersect. Two angles are linear if they are adjacent angles.
