A room is 10ft tall, 25ft long, and 15ft wide. The cost of paint is $12/gal. Each gallon of paint covers 200sqft. How many gallons of paint will you need (round to the nearest gallon) to paint the walls? * 3

< 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
