The formula to calculate the Roof Slope is:
\[ RS = \tan(\text{ra}) \]
Where:
The Roof Slope (RS) is the ratio of the vertical rise to the horizontal run of the roof, expressed as Y:1. It is calculated using the tangent of the roof angle (ra) in degrees. This measurement is important in construction and architecture to determine the steepness of a roof.
Let's assume the following value:
Step 1: Calculate the Roof Slope using the formula:
\[ RS = \tan(30^\circ) \approx 0.577 \]
The Roof Slope (RS) is approximately 0.577 (Y:1).
