Question 9: (6 points) Find the angle 0, in radians, in the given right triangle. The length of the side adjacent to O is 18 and the length of the side opposite 0 is 10. 10 18 Round your answer to the nearest hundredth. Question 10: (6 points) What percentage grade should a road have if the angle of elevation of the road is 4 degrees? (The percentage grade is defined as the change in the altitude of the road over a 100-foot horizontal distance. For example a 5% grade means that the road rises 5 feet for every 100 feet of horizontal distance.) Round your answer to two decimal places The road should have a(n). % grade
