Answer

Step 3: Use a calculator to find the arctan of 0.15. The result should be approximately 8.53 degrees.

Steps

Step 1 ：Step 1: Recall the formula to convert percent grade to degrees. The formula is \( \text{Degrees} = \arctan (\text{Percent Grade}) \)

Step 2 ：Step 2: Substitute the given percent grade into the formula. In this case, the percent grade is 15%, which can be written as 0.15. So, the formula becomes \( \text{Degrees} = \arctan (0.15) \)

Step 3 ：Step 3: Use a calculator to find the arctan of 0.15. The result should be approximately 8.53 degrees.
