Help on this please !! trig ratios

0.72

Step-by-step explanation: I’ve drawn the triangle out and have assumed that 21 is adjacent and 29 is the hypotenuse. In that case, 21/29 = 0.724

< 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
