Spencer picked 85 pears. gwen picked p fewer pears than spencer. write an expression that shows how many pears gwen picked.

type an asterisk ( * ) if you want to use a multiplication sign and a slash ( / ) if you want to use a division sign.

< 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
