Answer:

Option (3). 72°

Step-by-step explanation:

Angle of rotational symmetry = Central angle of a polygon

That means when we rotate the regular polygon by a central angle, polygon overlaps itself.

Central angle of a polygon with n sides = \frac{360}{n}

Where n = number of sides of the polygon

Therefore, central angle of a polygon with 15 sides = \frac{360}{15}

                                                                                     = 24°

Central angle tells us that after every 24° of rotation, polygon overlaps itself.

Angle of rotational symmetry may be 48°, 72°, 96°.....

Therefore, Option (3) is the possible angle of rotational symmetry.

He sum of three consecutive integers is −369−369. find the three integers.
Alinara [238K]
N + (n+1) + (n+2) = -369
3n + 3 = -369
3n = -366
n = -122

so the three consecutive integers are : -124 ; -123 ; -122

a cleaning company charges a flat fee of $8 and $30 per hour to clean a home. write an equation that can represent the situation
Andru [333]
In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
 
  30x+ 8 = 128

If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
