The focus of a parabola is located at (0,–2). the directrix of the parabola is represented by y = 2.

which equation represents the parabola?

y2 = –2x
x2 = –2y
y2 = –8x
x2 = –8y

< 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

uhhh idk u yolo?
