Answer:
114 degrees
Step-by-step explanation:
The formula to find the measure of all angles in a regular polygon is
, where n = total number of sides.
Thus, we substitute n for 10, and you get:

If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.
A central angle in a regular ten-sided polygon would be 144 degrees.
Answer:
Yes

Hi there!
I believe the answer would be A. Addition Property of Equality
Adding 0.36 to both sides of the equation and x being -5 means that the value is true, making it the A.
Hope this helps !
