Can somebody match these up for me?

Step-by-step explanation:

y=2x + 1 (1 , 3)

y= - 2x + 1 (1 , -1)

y=3x + 2(1, 5)

y = x +3(1, 4)

answer: 298143

step-by-step explanation:

< 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
