Question 1147355
.
<pre>

{{{x/2}}} = {{{(180-x)/3}}} + 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      = {{{510/5}}} = 102 degrees.    



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