Answer:
A. 45°
Step-by-step explanation:
The smallest interior angle measure of any regular polygon is that of an equilateral triangle: 60°.
___
The corresponding exterior angle measure for interior angle x will be its supplement: 180° -x. This value must be a divisor of 360° 360° is not evenly divisible by 180°-45°=135°.
The answer is 72 all u need to do plug in the numbers where the letters are
Here are your points (-9,-8), (-6,-2), (-2,-6)
X^2 + 8x + 16 =
(x + 4)(x + 4) or (x + 4)^2
