let the exterior angle be x
x=60°+80°(being one exterior angle is equal to two interior angle)
x°=140°

so... you tells us, which filling rate is the bigger and thus faster one?
Answer:
Y= 5/6x+5
Step-by-step explanation:
Okay same as before
the slope is rise over run
The rise is 5
The run is 6
So 5/6
And since ts rising from left to right its positive
The y-intercept which is the first point the line touches the Y axis is 5
So y=5/6x+5
