The Empire State Building weights about 7.3 x 10^8 pounds The one World Trade Center building weights abut 88,200,000 pounds what is the total weight in pounds of these two buildings? Expressing your answer in scientific notation in the from a x 10 what are the vaules of a and b

< 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
