Acertain triangle has a 30 angle and a 60 angle. which must be a true statement about the triangle.

a) two sides of the triangle have the same length.
b) the longest side is /3 times as long as the shortest side.
c) the longest side is twice as long as the second-longest side.
d) the second-longest side is /3 times as long as the shortest side.

< 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
