What is the value of x in the equation 2(x+3)=4(x-1) a.1 b.2 c.3 d.5

5

Step-by-step explanation:

2(x+3)=4(x-1)

2x+6=4x-4

6=4x-2x-4

6=2x-4

2x=6+4

2x=10

x=10/2

x=5

< 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
