Answer:
Angle = 64 Degrees
Supplement of Angle = 116 Degrees
Explanation:
Let the angle be "x"
We know
The complement of the angle is "90 - x"
and
The supplement of the angle is "180 - x"
From the statement given, we can write:
supplement is 12 LESS THAN twice the angle
The equation would be:
180 - x = 2x - 12
Now, we solve this for x:

The angle is 64 degrees
The supplement of the angle is 180 - 64 = 116 degrees
