please find the attached image for detailed calculation

Answer 2

Answer:

80 and 40 dude

Step-by-step explanation:

angle 1=120*

so

angle 1+angle 5=180*(angle 5 is the angle in the triangle in which angle 3 and 4 lie)

so

angle 5=60*

now

similarly angle 6=80*

and

angle 6 = angle 3(by alternate angle)

so

angle 3=80*

angle 5=60*

now

angle 3+angle 5+angle 4=180*

80*+60*+angle 4=180

and

angle 4=40*
