Consider the provided expression.

Add the numerator terms.

Now add the denominator terms as shown:

Thus, the simplified form of the provided expression is .

Hence, the correct option is A) 16/5.

180 square centimeters

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
