Answer:
your answer is 20 because you subtract 110 by 90 because that is a right angles and all right angles are 90 degrees.
Step-by-step explanation:
If the commutative property indicates that a+b=b+a with the problem being 98,551+2,841=2,841+n, its a pretty safe assumption that n would equal 98,551. a would be 98,551 as b would be 2,841.
