Solve for x , x-4/5= 6 3/4

Step-by-step explanation:

x - 4/5 = 6 3/4

6 × 4 + 3/4 = 27/4

x - 4/5 = 27/4

x = 27/4 + 4/5

x = 151/20

< 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
