Answer:
WPB
Step-by-step explanation:
Because it's larger than 90 degrees. And none of the other angles are obtuse.
An = 9 - n, since in the first row, that would be the only one to output 8 cans
By that rule 9 - 5 = 4 cans in the 5th row
The arithmetic sequences are 3rd one, and 5th one as they are increasing or decreasing by a constant rate of change
