The scatter diagram shows the results of 10 students in their french and Spanish test

(90, 16)

( x , y )

and I need to add more characters so, banana, am'i'right?

on friday there were 15 birds

< 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
