A roofing company claims they can haul away 755.2 hectograms of shingles every 90 minutes for trash. If they worked for 39 hours in a week, how many kilograms of shingles can they take to the trash?

The roofing company can take out 196.352kg of shingles.

       39 x 60 = 2340 minutes total

       2340 ÷ 90 = 26

       26 x 755.2 = 19635.2 hectograms of trash

        19635.2 ÷ 10 = 196.352kg

step-by-step explanation:

< 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
