When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
The measure of each exterior angle is 60° and the polygon has 6 sides ⇒ 4th answer
Step-by-step explanation:
In a regular n-side polygon:
- All sides are equal in lengths
- All angles are equal in measure
- The measure of each interior angle =
- The measure of each exterior angle =
- The sum of interior angle and exterior angle at a vertex is 180°
∵ The measure of an interior angle of a regular polygon is 120°
∵ The sum of interior angle and exterior angle at a vertex = 180°
∴ The measure of each exterior angle = 180 - 120
∴ The measure of each exterior angle = 60°
∵ The measure of each exterior angle =
- Substitute the measure of the exterior angle by 60
∴
- By using cross multiplication
∴ 60 n = 360
- Divide both sides by 60
∴ n = 6
∴ The polygon has 6 sides
The measure of each exterior angle is 60° and the polygon has 6 sides

Answer:
i say in blank one its 24cm
Step-by-step explanation:
Answer: There is difference of $660 in their paychecks.
Step-by-step explanation:
Since we have given that
Number of hours in one week they worked = 40
Amount of sales = $78000
Kent makes $10 per hour plus 3% on the amount of sales .
So, the equation for Kent becomes,
Similarly, Bradley only makes $7 per hour but he makes 4% on the amount of his sales .
So, the equation for Bradley becomes,
hence, the difference between of their paychecks is given by
Therefore, there is difference of $660 in their paychecks.
