Which of the following polygons has five lines of symmetry?
O A. Equilateral triangle
OB. Regular heptagon
O C. Regular pentagon
O D. Square
Answer:
pentagon have 5 sides, 5 symmetry lines.
So your answer is Option C.
The polygon with five lines of symmetry is a regular pentagon.
Option B is the correct answer.
What are regular polygons?A regular polygon is a closed shape that has straight sides of equal length and interior angles of equal measure.
This means that all of the sides and angles of a regular polygon are congruent (i.e., have the same size).
We have,
A regular pentagon is a five-sided polygon where all sides and angles are equal. It has five lines of symmetry, which means it can be divided into five congruent parts through lines that reflect the polygon onto itself.
To see why a regular pentagon has five lines of symmetry, consider drawing lines from each vertex to the center of the pentagon.
These lines divide the pentagon into five isosceles triangles, each with two equal sides and two equal angles.
Each of these triangles has a line of symmetry that passes through its vertex opposite to the equal sides, and through the midpoint of the base.
Thus,
The regular pentagon has five lines of symmetry.

A circle has a diameter of 17 inches, what is the circumference?
What is the center of the circle with this equation is (x+2)²+(y-4)=41?
Answer:
(h, k) is (-2, 4) and the radius is √41
Step-by-step explanation:
Compare the given equation with the general equation, which is good for circles with center at (h, k) and radius r:
(x - h)^2 + (y - 4)^2 = 41
Here the comparison shows that (h, k) is (-2, 4) and that the radius is √41.

Answer: 90 degrees
Since this is a regular polygon, you know that each side and angle will the congruent to each other. First, you need to find the sum of all the interior angles with the formula (n-2)⋅180 (n is how many angles the shape has) In this case there are 4 angles so (4-2)⋅180. Once you solve that we get 360 degrees for the sum of all the interior angles. Now that we know that, we can divide by 4 to see how many degrees each angle is. And the answer is 90 degrees.

Answer:
insufficient information7.2 miles18.5 milesStep-by-step explanation:
1. Insufficient information. We need to know the direction of one observer from the other, and the reference for the angles being measured.
__
2. See the first attachment. The law of sines tells you the distance r is ...
r = s(sin(R)/sin(S))
The angle at S is the supplement of the sum of the given angles:
∠S = 180° -35° -45° = 100°
Then the distance is ...
r = (10 mi)sin(45°)/sin(100°) = 7.1802 mi
The distance from Juan to the ship is about 7.2 miles.
__
3. See the second attachment. The law of sines tells you the distance 'a' is ...
a = b(sin(A)/sin(B))
a = (10 mi)sin(45°)/sin(50°) ≈ 18.4612 mi
The distance from airplane B to the airport is about 18.5 miles.
