If figure e is multiplied by a scale factor of 2.5, reflected over the y-axis, and translated 1 unit right and 4 units up, which is true about e′?

Answer is A

E′ has the same shape but not the same size as Figure E.

< 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
