    I believe I hvae a simpler solution. Drop a perpendicular from the join between the coins, thus halving the angle X and it also extends the common side of the coins. If you were an ant crawling along that side, you’d have to change direction by an angle X/2 to be able to walk along the next side. And you’d have to do this 12 times to walk all around the coin. But that is one complete turn of 360*. Thus X/2 = (360/12)* and X=60*.
