A skateboard ramp has a height of 3 feet and a horizontal of 7 feet. What is the angle of 0 of the ramp?

When we have a right triangle with sides and angles, we use basic trigononemetry. Since we know the vertical leg (height of ramp) and horizontal leg (base length of ramp), we use the inverse tangent function to find the angle.

θ = tan-1 (height of ramp / base of ramp) θ = tan-1 (2.5 / 6) θ = tan-1 (5 / 12)
