Find the length of the missing side. the triangle is not drawn to scale.

6

Step-by-step explanation:

a^2 + 8^2 = 10^2

a^2 + 64 = 100

a^2 = 36

sq root of a = sq root of 36

a = 6

< 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
