A skateboard ramp is 17 inches high and rising an angle of 25° how long is the base of the ramp?

36.46 inches

Step-by-step explanation:

The tangent of the angle is the ratio of the height to the base length:

Tan = Opposite/Adjacent

tan (25°) = (17 in) / (base)

base = (17 in) / tan (25°) ≈ 36.46 in

The base of the ramp is about 36.46 inches long.
