A mass 20 (in grams) suspended from a string of length 94 (in cm) forms a simple pendulum. If its amplitude is θ0 (in degrees), during what fraction of its period can the pendulum be found between + θ ° and - θ °? The initial amplitude is small enough that the motion is simple harmonic to a very good approximation. Express your answer in terms of the given variables.
