Solve a = d+c/b
Help me please

Option A is the correct

Step-by-step explanation:

a=d+c/b

Now we have to solve for d

Multiplying b on both sides

a*b=d+c/b*b

ab=d+c

ab-c=d

I hope this will help you:)

answer: okw

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
