Question

please help me to solve this.​

Answer 1

angle 2 = 180°-30°(linear pair)

= 150°

angle 3 = angle 1 (Vertically opposite angle)

= 30°

Answer 2

Step-by-step explanation:

let 2 be x and 3 be y

due to the linear pair

30+x=180°

x=180-30

x=150°

again apliyng linear pair

150+y=180°

y=180-150

y=30°
