Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 75 miles per hour. The eastbound train travels at 85 miles per hour. How long will it take for the two trains to be 256 miles apart?

< 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
