Which set of coordinates satisfies equations 3x-2y=15 and 4x-y =20?
A. (2,-7)
B. (1,-6)
C. (0,-7.5)
D. (5,0)

Its A

Step-by-step explanation:

Sorry I don't have time but it is A I had this before

< 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
