From my research, the image below belongs to the question. From what is seen in the image, there are 2 arcs already drawn with respect to the new vertex. The third arc corresponds to the point where the line DM is made. This line is similar to line BC. So at the point where the second and third arcs would meet, it would be a point similar to a point on line AB.
Bluegill
3/5 × 1100
660
catfish
70% × (1100-660)
70% × 440
308
so not catfish or blue gill
1100 - (660 + 308) = 132
The answer is that his average is 75.5 for the second nine weeks
