As it is obvious from the figure that both angles are forming linear pair (straight line).So sum of these angles will be 180°.

Now form equation

$\large \tt : \implies \: \: (x+65)+(x+25)=180°$

$\large\tt : \implies \: \: x+65+x+25=180°$

$\large \tt : \implies \: \: 2x+90=180°$

$\large \tt: \implies \: \: 2x=180°-90$

$\large \tt : \implies \: \: 2x=90°$

$\large \tt : \implies \: \: x= \frac{90 \degree}{2}$

$\large \boxed { \tt \blue{: \implies \: \: x=45 \degree}}$
