Finding the Measurement of a Half Angle
Now, we will return to the problem posed at the beginning of the section. A bicycle ramp is constructed for high-level competition with an angle of formed by the ramp and the ground. Another ramp is to be constructed half as steep for novice competition. If for higher-level competition, what is the measurement of the angle for novice competition?
