Y+5=2(x+1)
Only (5,10)
Only (-1,-5)
Both
Neither

only (-1, -5)

Step-by-step explanation:

If x= -1 and y= -5

(-5)+5= 2((-1)+1)= 0

< 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
