Layla was late to class 5 times in the month of October. Each time she was late she 4 1/2 minutes of class. How many total minutes did she miss in the month of
October?

i can you answer this question sweetie!

step-by-step explanation:

< 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
