Answer:

Step-by-step explanation:

40+40=3x+20(sum of two interior opposite angle is opposite to the exterior angle formed)

=80=3x+20

=80-20=3x

=60/3=x

=20=x

substitute the value of x

=3x+20

=3*20+20

=60+20

=80

v+71=107 degree(sum of two interior opposite angle is equal to the external angle formed)

=v=107-71

=v=36 degree
