How many triangles can be constructed with 3 angles, each measuring 63°?

0

a triangle's angles should add up to be 180 degrees. Three angles of 63's sum is 189

< 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
