Understanding Ramp Elevation

The video tutorial explains how to determine the angle of elevation of a ramp using trigonometry. It begins by identifying the ramp's dimensions and the relevant sides of the triangle formed. The tutorial then demonstrates how to use the sine function and its inverse to calculate the angle, concluding with the solution that the ramp has a 30° angle of elevation.
