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:
The rigth answer is, x = 1
Step-by-step explanation:
As:
f (x) = 3/4 x + 12
They separate the terms:
3/4 x = 12
Then, what you are multiplying happens to divide:
x = 12/1/3/4
Media are divided by means and ends with ends, and we have as a result that:
x = 3/3 = 1
78×45/100
=35.1. As a result, 35.1 is 45% of 78. Hope it help!
