A road climbs at an 8 degree angle with the horizontal. What is the grade of the Road.

To calculate the grade of a road, you need to determine the percentage of the road's vertical rise compared to its horizontal distance. In this case, the road is climbing at an 8-degree angle with the horizontal.

To find the grade of the road, you can use the formula:

Grade = Tan(angle) * 100

In this formula, Tan(angle) represents the tangent of the angle (in this case, Tan(8)).

Let's calculate the grade of the road:

Grade = Tan(8) * 100

Using a scientific calculator or an online calculator that supports trigonometric functions, you can find that Tan(8) is approximately 0.1405.

Grade = 0.1405 * 100 = 14.05

Therefore, the grade of the road is approximately 14.05%.
