Answer:
The measure of the angle is <u>64</u> degree.
The measure of the supplement is <u>116</u> degree.
Step-by-step explanation:
Let the measure of the angle be 'x'.
Given:
Supplement of the angle is 12 less than twice the measure of the angle.
Twice the angle means 2 times of the angle which is
and 12 less means 12 is subtracted from
.
So, supplement of the angle = 
Now, by definition of supplementary angles, if two angles are supplement of one another, then their sum is 180 degrees.
Therefore, the sum of the given angles = 180°

⇒ 
The measure of the supplement = 
The measure of the angle is <u>64</u> degree.
The measure of the supplement is <u>116</u> degree.
