Show that 220 and 284 are amicable numbers. will give brainliest.

Amicable numbers are a pair of numbers such that the sum of their

proper divisors (not including itself) equals the other number.

Because amicable numbers must come in pairs, they are sometimes called

amicable pairs or amicable partners.

For example, show that 220 and 284 are amicable numbers:

  First, find the proper divisors of 220:

     1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110

  If you add all these numbers together, you can see they sum to 284.

  Now find the proper divisors of 284:

     1, 2, 4, 71, 142

  These sum to 220.

Thus, 220 and 284 are a pair of amicable numbers.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
