Given z = 8 and x = 6 what is the ratio of z to x

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. The ratio  of x to z in the simplest form would be as follows:

x/z = 6/8 ÷ 2/2= 3/4

< 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
