Hi, there--
.
Two angles are supplementary when the sum of their measures is 180 degrees.
.
Let x be the measure of the first angle.
.
The measure of the second angle is "2 more than double the other angle." We can write that relationship as 2x+2.
.
The sum of the angle measures is 180 degrees, so we can write the equation,

.
Now we solve for x.





.
The equation x = 59 1/3 means that the first angle measures 59 1/3 degrees. The second angle measures 2 more than double, so its measure is 2*(59 1/3)+ 2 = 120 2/3 degrees.
.
Be sure to check your answer. Is the sum of their measures 180 degrees?

.
Check!
.
That's it. Feel free to email via gmail if you have questions about the solution.
