Mark is going to work, he drives 70 miles at 35 mph, how many minutes does it take Mark to get to work?

time = 120 minutes

= 120 min

= 02:00:00

= 2 hours, 0 minutes, 0 seconds

< 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
