Answer:
Triangle Sum Theory
Step-by-step explanation:
You add all the angles to get 180
To get the constant of proportionality (unit rate) you must find the miles driven in 1 hour. To get this you simply divide 200 by 4...
200÷4=50
So, the constant of proportionality is 50 mph.
The answer for this question is 5 because 5 shows up the most. The mode is the number that shows up more often then any other numbers
