Arrow Length - refers to the length of the arrow shaft. Arrow size - refers to the spine (stiffness) of the arrow. The shaft size is always referring to the diameter of the shaft, the wall thickness of the shaft and the distance that the arrow shaft will flex before it bends or breaks.
The sine of 30 degrees is 0.5 so the elevation from our shooting position to the target is SIN30(120) or 0.5 x 120 = 60 feet. Our arrow must not only travel 60 feet higher than one shot horizontally but the horizontal component of flight will only be 103.9 feet instead of 120 feet.
