A) 94x^2+15x-25
b)34^2+15x-25
c)27x+3
d)34x^2-15x-25

d) 34x^2 - 15x -25

( (8x + 5) * (8x - 5) ) - 5x(6x +3 )

= 64x^2 - 25 - 30x^2 - 15x

= 34x^2 - 15x - 25

< 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
