angle 3 is 50

angle 4 is 10 May be

Answer 2

Answer:

1=60°

2=60°

3=50°

4=10°

Step-by-step explanation:

(interior triangle =180°)

Angle 1 is 60° as it is linear pair of 120°

Angle 2 is the third Angle of the triangle where 1st Angle is 60° and another angle is also 60°

So 2=180-60+60

180-120

60°

Angle 3 is on a straight line between 60 and 70

so 3=180-60+70

180-130

50°

Angle 4 is in a triangle where one angle is 120 and other(3)' is 50

so 4=180-120+50

180-170

10°
