Hi!

To find the semmetry between the nonagon just do this:

360 / 9 = 40

The regular nonagon has rotational symmetry of 40 degrees!

central angle of 360° is divided into 9 equal angles each with a measure


360°/9=40°

I think they are congruent because two of their lines are the same and the both have a 90 degree angle. I think they are congruent from the SAS postulate.

How do I solve this problem step by step?
Rom4ik [11]

Answer:

V = 3

Step-by-step explanation:

<u><em>Given:</em></u>

<em>Perimeter of the pentagon is 52 units.</em>

<em>Solve for value of v.</em>

<u>Solve:</u>

<em>Let first put it into a equation base on the given;</em>

<em>6v + 8 + 8 + 3v + 1 + v + 5 = 52</em>

<em>Add the numbers</em>

<em>6v + 22 + 3v + v = 52</em>

<em>Combine like terms</em>

<em>10v + 22 = 52</em>

<em>Subtract 22 from both sides</em>

<em>10v + 22 - 22 = 52 - 22</em>

<em>Simplify</em>

<em>10v = 30</em>

<em>Divide both sides by 10</em>

<em>10v/10 = 30/10</em>

<em>Simplify</em>

<em>v = 3 </em>

<em>Check Answer:</em>

<em>6(3) + 8 + 8 + 3(3) + 1 + (3) + 5 </em>

<em>18 + 8 + 8 + 3(3) + 1 + (3) + 5 </em>

<em>18 + 16 + 9 + 1 + 8</em>

<em>18 + 16 + 9 + 9</em>

<em>18 + 16 + 18</em>

<em>36 + 16</em>

<em>52</em>

<em>Hence, v = 3</em>

Which equation does not represent a direct variation?
tatuchka [14]
Okay I think there has been a transcription issue here because it appears to me there are two answers. However I can spot where some brackets might be missing, bear with me on that.

A direct variation, a phrase I haven't heard before, sounds a lot like a direct proportion, something I am familiar with. A direct proportion satisfies two criteria:

The gradient of the function is constant s the independent variable (x) varies

The graph passes through the origin. That is to say when x = 0, y = 0.

Looking at these graphs, two can immediately be ruled out. Clearly A and D pass through the origin, and the gradient is constant because they are linear functions, so they are direct variations.

This leaves B and C. The graph of 1/x does not have a constant gradient, so any stretch of this graph (to y = k/x for some constant k) will similarly not be direct variation. Indeed there is a special name for this function, inverse proportion/variation. It appears both B and C are inverse proportion, however if I interpret B as y = (2/5)x instead, it is actually linear.

This leaves C as the odd one out.

I hope this helps you :)
