Which inequality has a closed circle when it is graphed on a number line? a) x > 0.4 b) x > -3 c) x < 4 d) x _> 3

the answer is D) X _> 3

Step-by-step explanation:

the answer is D) X _> 3

< 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
