Let's solve ~

[tex]\qquad \sf  \dashrightarrow \:40 + x + 25 = 180[/tex]

[tex]\qquad \sf  \dashrightarrow \:x + 65 = 180[/tex]

[tex]\qquad \sf  \dashrightarrow \:x = 180 - 65[/tex]

[tex]\qquad \sf  \dashrightarrow \:x = 115[/tex]

I hope you understood the procedure, please let me know if you have any doubts
