An angle marking is like a meter stick marking. The marking of 1.2m on a meter stick only means an object is 1.2m long if the object starts at zero meters. If it starts at 0.2 meters then the object is really 1.0 meters long. You will be making angle calculations from angle markings in a similar fashion.

Given a green marking of 211 degrees and a straight-on marking of 254 degrees, how much has the light bent?
