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.
Answer:

Step-by-step explanation:
Given
Kano = 45;
Kwara = 410;
Ogun = 105;
Ondo = 126;
Oyo = 154
Total Distribution = 840
Required
Determine the angle subtended by Ondo (in a pie chart)
The general formula to calculate subtended angle in a Pie chart is;

In this case of Ondo
Frequency = 126
Total Frequency = Total Distribution = 840
Substitute these values in the given formula;




<em>Hence, the angle subtended by Ondo is 54</em>
Answer:
x = 24
Step-by-step explanation:
x - 16 = 8
Isolate the x
You can do this by adding 16 to each side.
x - 16 = 8
+16 +16
8 + 16= 24
x = 24
