  1. It's a bit tricky, but you picked a good angle.

    9 3/8 degrees is 1/8 of 75 degrees.
    75 = 90-15.

    Make a 60deg angle and bisect it twice. That will give you 15deg.

    Subtract that from 90deg, and you will have 75deg.

    Bisect that angle 3 times, and you will have 9 3/8 degrees.

    *whew*
