Answer:

I will say u about triangles.. ..

Step-by-step explanation:

To find the exterior angles u need to do sum of the opposite angles of the exterior angles

Now let's find...

1)angle A + angle B=x where,xis exterior angle

so,

50+60=x

x=110

2)40+40=80

x=80

3)50+60=110

x=110

hence, we found all the exterior angles means x values...
