What is the value of x?
A.
11
X + 4
O 2
O 3
O 6
O 7
B X+1E

the value of x is 0 in thus case

< 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

a=area

step-by-step explanation:
