To find the angles 1 and 2:

In the above triangle, the angles opposite to the equal sides are equal.

Let us take,


\angle1=\angle2=x

So, using the angle sum property of a triangle


\begin{gathered} 55+x+x=180 \\ 2x=180-55 \\ 2x=125 \\ x=62.5^(\circ) \end{gathered}

Hence, the angles are


\begin{gathered} \angle1=62.5^(\circ) \\ \angle2=62.5^(\circ) \end{gathered}
