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.

The area of a square is
harkovskaia [24]

square has 4 equal sides

so A = 144 =  12^2

A = L x W

= W. W

= W^2

12^2 = W^2

so W = 12

answer: one side of the square = 12

1/2 (x-4/5)=3/5
malfutka [58]
1/2x-2/5=3/5       (BTW I got 2/5 by reducing 4/10)
1/2x=7/5             (BTW I got 7/5 by moving 2/5 to the other side)
Then do 7/5 times 2 and you get 14/5

14/5

Write an equivalent expression to
mel-nik [20]
1. Distributive Property. 
<span>4(3a + 7) + 3(2a + 5)
12a + 28 + 6a + 20

2. Combine like terms
12a + 28 + 6a + 20
18a +48


The equivalent expression is 18a + 48. If a = anything then the expressions will still be equivalent.
