We have a triangle with sides of (8x + 2) , ( 5x - 4) , and ( 9x + 3). Explain how you find the perimeter of a triangle.

Step-by-step explanation:

This is incomplete question as the perimeter of the triangle is not give

< 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
