Let's first get the representation of tan
We also need to understand how to convert radians to degrees

For question 1
since tan > 1
It must be in either first quadrant or third quadrant as shown in the diagram above
1) 185.16 - 18.99 = 166.17
2) divide 166.17 by 0.87 = 191
3) he drove the truck for 191 miles
