The total bill of a meal at a restaurant is 25x – 115. five friends agree to split the cost of the meal equally. what could you do to find the amount that each person must pay? explain.

Step-by-step explanation:

If 25x - 115 is the total amount, then this needs to be divided by 5:

This division can also be written like:

Which gives the result of:

5x + 23 , which is the amount that each person must pay.

< 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
