. write the set in roster form


A={x : x is a two digit natural number such that the sum of its digits is 8}

Answer 1

The Two digit numbers whose sum of their digits is 8 are :

17 : because 1 + 7 = 8

26 : because 2 + 6 = 8

35 : because 3 + 5 = 8

44 : because 4 + 4 = 8

53 : because 5 + 3 = 8

62 : because 6 + 2 = 8

71 : because 7 + 1 = 8

80 : because 8 + 0 = 8

So the set A in Roster form is :

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