weeks
I guess =ay=6-3x= ay/y=6-3x/y= a=6-3x/y
Answer: C
Step-by-step explanation:
We know that
, and thus by the exterior angle theorem,

Thus, 
Answer:
the measure of the angle is 72
x=36
Step-by-step explanation:
we can make an algebraic equation using the info given
2x+80=152
2x=72
x=36
the measure of the angle is 72
The answer is A because it has a variable. HOPE THIS HELPS!!! <3
