Proving that G matches L: [.5pts per prompt = 5pts] Finish the Inductive Proof from week 10. L = {w | w has an equal number of a’s and b’s} // we have 3 non-terminals 1 S -> aB // starts with a 2 S -> bA // starts with b // comes to A after starting with b. A means balance that b with a. 3 A -> a 4 A -> aS 5 A -> bAA // comes to B after starting with a. B means balance that a with b. 6 B -> b 7 B -> bS 8 B -> aBB

< 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

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
