.

 =  + 25.


It is your basic and starting equation, which follows the problem's description.


To solve this equation, multiply both sides by 6. You will get


3x = 2*(180-x) + 150,


3x = 360 - 2x + 150,


3x + 2x = 360 + 150


5x      = 510


 x      =  = 102 degrees.    



ANSWER.  The angle's measure is 102 degrees.  Its supplement measure is  180-102 = 78 degrees.
