Solve triangle XYZ, given XY = 90°, XY = 12, and ZX = 61°.= Make your angle measures correct to the nearest degree and side measures to 1 decimal place.

Precalc

< 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
