You have 120 minutes this evening to exercise, eat dinner, and clean your room. It takes you 45
minutes to exercise and 25 minutes to eat dinner.
What possible amounts of time can you spend
cleaning your room?

50 minutes

Step-by-step explanation: subtract 120 by 45 equals 75, now subtract 75 by 25 and that equals to 50

< 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
