A factory produces 272 chairs in an 8 hour shift. If the factory produces the same number of chairs each hour, how many chairs does it produce in 30 minutes?

17 chairs.

Step-by-step explanation:

If they make the same amount of chairs per hour they make 34 chairs every hour because 272 divided by 8 is 34, 30 minutes is half of one hour so they make half as many chairs and 34/2 is equal to 17

< 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
