The angle opposite to equal sides are equal. So two angle are equal to 65 degree each and one angle is (3y + 2).
Determine the value of varaible y, by using angle sum property of triangle.
[tex]\begin{gathered} 3y+2+65+65=180 \\ 3y=180-132 \\ =48 \\ y=\frac{48}{3} \\ =16 \end{gathered}[/tex]So value of y is 16.
