Which of the following is a solution of x2 + 6x = -22? -3+i √ 13
-3 +i √ 52
-6+i √ 13
-6+ i √ 52

55/i dont know i do it for the points

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
