Answer:
Can I have branliest please!
The measurement is 110 degrees
Step-by-step explanation:
To find there are two ways to get it
There is a rule that states to find one of the exterior angles you have to add the other two angles that are not supplementary to the exterior one.
So, you can add 40 + 70 to get 110 degrees
OR
You can find the missing angle in the triangle to get 70
Angle MON and Angle MOP are supplementary
so you can subtract 70 from 180 to get 110
Hope this helps!
