Answer:
Distance between two cities is 193.94 miles.
Step-by-step explanation:
We have,
Madison and Wisconsin have latitudes 43.0731°N and 45.9172°N respectively.
Thus, their difference is 45.9172°N - 43.0731°N = 2.8441°
We assumed, the diameter of earth is 7917.5 miles.
So, the radius = 
= 3958.75 miles
So, using the cosine formula, we have,
i.e. 
i.e. 
i.e. 
i.e. a= 193.94 miles.
Hence, the distance between two cities is 193.94 miles.
Answer:
78
Step-by-step explanation:
Since the two angles at the bottom are congruent, you would the two equations equal to each other. So it would be:
5x-19=2x+11
Once you simplify, you will find that x= 10.
Then you plug in x for both equations, so 5(10)-19= 31 and 2(10)+11= 31
So you add up the sides: 31+31+16= 78
