Answer:
12.9
Step-by-step explanation:
Okay, this is a written proof so what you have to do is list the steps. I am going to try my best to solve this problem...
Using Triangle sum theorem you add all the angles to make 180. So 47.7+51.1+<1=180
98.8+<1=180
-98.8 -98.8
<1= 81.2
This is a linear relationship as the rate of change is constant, ie constant velocity. And the slope represents the velocity, and slope is:
m=(y2-y1)/(x2-x1)
m=(50-25)/(2-1)=25/1
m=25
So the rate of change is 25 mph
