What is the value of z in the equation 3z − 7 = 14? 3 4 7 21

Option C is correct

the value of z is, 7

Step-by-step explanation:

Given the equation:

Add 7 to both sides we get;

Simplify:

Divide both sides by 3 we get;

z = 7

Therefore, the value of z is, 7

< 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
