Two angles are said to be supplement when their measure add up to 180 degrees.
Assume that the angle we are looking for is a and its supplement is s (I used s instead of x).
a + s = 180
a = 180 - s ......> equation I
We know that <span>the measure of the angle is eight times greater than its supplement.
This means that:
a = 8s ......> equation II
Substitute by equation II in equation I to get s as follows:
180 - s = 8s
180 = 9s
s = 20 degrees
Substitute in equation I to get the measure of the angle as follows:
a = 180 - s = 180 - 20 = 160 degrees
Based on these calculations:
The measure of the angle is 160 degrees
The measure of its supplement is 20 degrees</span>

The penny is a circle, the diameter is a line segment that passes directcly through the center of a circle, the answer is diameter.
Answer:
20 sides
Step-by-step explanation:
The formula that relates interior angles with number of sides is:

Where
n is the number of sides.
We know each interior is 162 degrees, so we substitute and cross multiply and solve for n:

THus, the polygon has 20 sides
