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 = 
Where n = number of sides of the polygon
Therefore, central angle of a polygon with 15 sides = 
= 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.
The square root of 58 is:

Answer:
y = 2/7 or y = 14/25
Step by Step explanation:
sorry about the last answer
simplify both sides of the equation, then isolate the variable
I took a picture of the work instead ^^
