When the digits of a two digit number are reversed, the new number is 54 less than the original number. If the sum of its digits is 8 what is the original number

71

Step-by-step explanation:

When 71's digits are reversed you get, 17.

When 17 is subtracted from 71 you get, 54.

When 7 and 1 are added together you get, 8.

Therefore, the original number is, 71.

Hope this helped! :)

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
