15 pts, Solve a right triangle. Please write your answers as it says on the mandate, Thanks!

Hence,

Hope it helps you. Please don't mind my rude handwriting. Just pretend it get bent due to a cyclone.

im sorry but no. i just need to answer for 50 poonts oof

< 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
