A student is conducting an expirement to determine how far a ball will roll down a ramp based on the angle of the incline what is the independent variable and dependent

Angle of inclination is the independent variable.

Distance covered by the rolling ball is the dependent variable.

Explanation:

An independent variable is the one whose variation is not dependent on the value of any other variable while dependent variable changes its value with a change in the independent variable.

In this experiment, angle of inclination (angle between a line and the x-axis) is an independent variable whereas the the distance covered by the rolling ball is a dependent variable which will vary with a change in angle of inclination.
