We have the following:
In the figure we can see that the angle x and the angle y are equal.
Now, we know that inside a triangle, the sum of the angles is always equal to 180 °
Therefore:
[tex]\begin{gathered} 180=x+y+110 \\ x=y \\ 180=y+y+110 \\ 2y=180-110 \\ y=\frac{70}{2} \\ y=35 \\ x=35 \end{gathered}[/tex]
Therefore, x = 35° and y = 35°
