What is the value of angle X and angle Y in the triangle diagram below?

Sum of two interior angles=exterior angle
[tex]\\ \rm\Rrightarrow 45+65=y[/tex]
[tex]\\ \rm\Rrightarrow y=110[/tex]
[tex]\\ \rm\Rrightarrow x+y=180[/tex]
[tex]\\ \rm\Rrightarrow x+110=180[/tex]
[tex]\\ \rm\Rrightarrow x=70[/tex]
