7. In a regular polygon, each exterior angle is equal in measure. If the exterior angle is 72degrees, then the number of sides in the polygon can be found by dividing 360degrees (the total degrees in a circle, or the sum of exterior angles in any polygon) by the exterior angle.
Therefore, the regular polygon has 5sides.
8.The distance between point A (2,2) and point B (7,2) in a Cartesian plane is 5 units.
The answer is 5 units because the x-coordinates of point A and point B are the same, while the y-coordinates differ by 5 units.
