What is the value of x?

x =

(secants, tangents, and angles)

The value of x is

Step-by-step explanation:

we know that

The measurement of the external angle is the semi-difference of the arcs which comprises

so

In this problem

solve for x

< 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
