= Problem Seven- Design a Road = =Workers are designing a road to go over a mountain. They want the road to have a maximum grade of 14%. The lowest gap in the mountain that they are going to go over has an elevation of 1625 feet above sea level. The road will start at an elevation of 414 feet above sea level and meet up with a road on the other side at an elevation of 633 feet above sea level. What is the minimum length of the road to meet these requirements? What is the average angle of elevation for this road? =

How do you find the hypotenuse, aka the distance of each side of the road?:
__Sin7.97__=__Sin90__ 1211 a= 8734.36 ft.

__Sin7.97__=__sin90__ 922 b= 6649.62 ft.

In total, the shortest distance of the hypothetical road is 15,383.98 feet! The average angle of elevation is 7.97 degrees.
