Create an equivalent expression that includes a set of parentheses that make the value of the expression 5. Remember, you can have two or more numbers within the set of parentheses. 32+10-8+2-3 is the number

b

step-by-step explanation:

b

< 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
