Answer:
[tex]\boxed{\tt x=45^o}[/tex]
Step-by-step explanation:
The two angles together are supplementary, which means that they add up to 180°
[tex]\tt (2x+45)^o+x^o=180^o[/tex]
Now, let's solve for x:-
[tex]\tt 2x+45+x^o=180^o[/tex]
[tex]\tt 3x+45^o=180[/tex]
[tex]\tt 3x=135^o[/tex]
[tex]\tt x=45^o[/tex]
