Four less than six times a number equals 73

Let the number be

4 less than < 6 times a number = 73

A/Q

Now, let's check it whether the value is correct or not.

{ Use BODMAS rule here }

Now come to the point

➝ 12.83 × 6 - 4 = 73

➝ 76.98 - 4 = 72.98 which is equal to 73.

As we know that if after decimal number exceeds 5 it is converted to its next number.

< 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
