What percent slope rises at a 45 degree angle?

A slope expressed as a percentage is calculated by comparing the vertical rise to the horizontal run. For a slope that rises at a 45-degree angle, the vertical rise and horizontal run are equal. This means that if you have a rise of 1 unit vertically, you also have a run of 1 unit horizontally.

To find the percentage of this slope, you take the vertical rise (1) and divide it by the horizontal run (1), which equals 1. You then multiply that result by 100 to convert it into a percentage.

Thus, the calculation looks like this:

( \text{Slope Percentage} = \left( \frac{\text{Rise}}{\text{Run}} \right) \times 100 = \left( \frac{1}{1} \right) \times 100 = 100% )

Therefore, a 45-degree angle corresponds to a slope of 100 percent, confirming that the correct answer is indeed 100%.
