If a coffee table has a sale price of $54 and is 25% off, what was the original price?

$72

Step-by-step explanation: You have to realize that $54 is 75% of the original price, meaning that $54 is 3/4 of the original. Therefore, you must divide 54 by 3 to get 18, which is 25% of the origianl price. Since you now know what 25% of the original price is, you just have to add 18 to 54 to get $72. 72 dollars is 100% of the original price of the coffee table.

< 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
