1 point 3) ATTACH WORK FOR THIS QUESTION - WORTH 3 POINTS: Evaluate the
following expression below.

(3⁰)×(4‐²)×(2³)

1×1/16×8

1/2

so th3 answer is option c.

< 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
