1. in the figure, x∥y and a is a transversal that crosses the parallel lines. which angle pair forms corresponding angles?

a. ∠1 and ∠4

b. ∠6 and ∠7

c. ∠1 and ∠5

d. ∠3 and ∠6

< 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
