Now, we solve the square:
Now, we add the values:
Now, we take the square root to both sides:
Solving the operations:
Therefore, the length of the hypotenuse is 22.361 kilometers.
Use the law of cosines to find a: 
So to use the given numbers you get:
Which would come out to equal about 35.94
so a=35.9
