Sports test, can Xiaodong estimate the distance of throwing sandbags?

In sports test, we can estimate the distance Xiaodong throws sandbags. Because after each throwing, we should use a tape measure to measure the impact point of sandbags from the throwing point and record it. Take the throwing point as the origin, draw an arc at regular intervals, and mark the length from the center of the circle on the arc. Draw a straight line from the throwing point to the throwing direction and mark the number of meters. When throwing, throw along a straight line, and you can estimate the distance by looking at the landing point on the straight line.
