Answer:
The angle is 30
and its supplement is 150
Step-by-step explanation:
Let the angle be x
The supplement of an angle is 180 minus that angle
So the supplement here is 180 -x
Now, the supplement of the angle is 30 less than 6 times the angle;
Thus;
180-x = 6x -30
180 + 30 = 6x + x
7x = 210
x = 210/7
x = 30
the supplement is 180 - x = 180 -30 = 150
