What’s the next step to solve the equation -2(n+3)= 9

-15/2

Step-by-step explanation:

The next step would be to distribute the negative two through the parenthesis,

-2n-6=9

then you add the six, -2n= 15

then you divide by 15 by negative 2 and get -15/2

< 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
