Answer:- In a regular decagon, there are 10 reflectional symmetries.


Reflectional symmetry or Line of symmetry divides a figure into two equal halves so that if you flip the half image over the line of symmetry, the figure would look same.

A regular decagon has 10 vertices and 10 edges.

where 10 vertices forms 5 lines of symmetry.

and 10 edges forms 5 lines of symmetry.

⇒Total lines of symmetry in a decagon =5+5= 10

Thus, In a regular decagon, there are 10 reflectional symmetries.

The traffic light is approximately ___ feet tall ?
jolli1 [7]

Answer:

Base at the top should be the same length, thus 20ft.

right triangle thus 90 degrees angle.

180 - 90 - 40 = 50

20ft/sin50 = Height/sin40

Height of the traffic light = 16.78

16.78 + the height of Andrew eyes ( 5ft) = 21.78

Tell wheather the system has one solution, infinitely many solutions, or no solution.
ipn [44]
<h3>Answer:</h3>
  1. One solution: (x, y) = (2, 0)
  2. Infinitely many solutions: 2x -5y = 17
<h3>Step-by-step explanation:</h3>

1. When you put the second equation in standard form, it is ...

... 5x +3y = 10

This is a different equation than the first one, so there will be one solution where the lines interect. (Adding the two equations gives 10x=20 ⇒ x=2. Since adding or subtracting y gives the same result, y must be zero.)

2. When you put the second equation in standard form, it is the same as the first:

... 2x -5y = 17 . . . . . divide the equation by 3

That is, any (x, y) values that satisfy the first equation will also satisfy the second equation (since they are the same). There are an infinite number of (x, y) values that do so.
