    oh ok I see! terrific..there was another way I looked at it too! if you look at the picture angle K has one arc which measures 60 degrees, and angle M has two arcs! so I was thinking that I could multiply 60 times 2!

    the arc simply mean that they are different angles

    they dont have to be different by a factor of 2 tho
