Answer 1

Answer:

{17,26,35,44,53,62,71,80}

Step-by-step explanation:

let digit be ab

given a+b=8

let take a=1 then possible value for b is 7

so number is 17

let take a=2 then possible value for b is 6

so number is 26

let take a=3 then possible value for b is 5

so number is 35

let take a=4 then possible value for b is 4

so number is 44

let take a=5 then possible value for b is 3

so number is 53

let take a=6 then possible value for b is 2

so number is 62

let take a=7 then possible value for b is 1

so number is 71

let take a=8 then possible value for b is 0

so number is 80

Answer 2

Answer:

• H = {17,26,35,44,71,62,53,80}
