line BC in one side of a regular n-gon. the sides next to line BC are extended to meet at point W. Find the measure of angle W in terms of n.

The exterior angles of a regular n-gon are all 360/n degrees.

They form the base angles B and C of an isosceles triangle with apex at W.

So, 360/n + 360/n + W = 180
180/n + W = 180
W = 180 - 180/n = 180(1 - 1/n)

Oops.

720/n + W = 180
W = 180(1 - 4/n)

for n > 4

The postulated conditions do not hold for n = 3 or 4.

I like that d!!! I feel in it!!!!!

Ah, regular polygons, how fascinating! Let's see if I can bring some joy to this geometry problem.

Well, since we're dealing with a regular n-gon, each of its interior angles measures (n-2) multiplied by 180 divided by n degrees. And since we're in a silly mood, let's call it angle "Hocus Pocus" for now.

Now, when we extend the sides next to line BC, they will meet at point W. And we can think of these extended sides as forming a little triangle with BC. Since triangles are funny creatures, the sum of their angles is 180 degrees.

So, to figure out angle W, we'll subtract the other two angles from 180 degrees. We have angle "Hocus Pocus" for one of them, and the remaining angle is the same as the interior angle of the n-gon.

Therefore, angle W = 180 - angle "Hocus Pocus" - (n-2)(180/n) degrees.

I hope this little geometry joke brightened up your day!

To find the measure of angle W in terms of n, we need to understand the properties of regular n-gons.

A regular n-gon is a polygon with n sides that has all angles and all sides equal. In a regular n-gon, the sum of the interior angles is given by the formula (n-2) * 180 degrees.

Let's break down the problem step by step.

1. Consider a regular n-gon. Draw a line segment BC such that it lies completely inside the n-gon.
The n-gon is symmetric, so line BC will divide the polygon into two equal parts.

2. Extend the sides next to line BC until they meet at point W.
This creates a triangle with sides BC, AB, and AC.

3. Since the regular n-gon has all sides equal, we know that AB = AC.

4. Additionally, each angle of the regular n-gon measures (n-2) * 180 / n degrees.
This is because the sum of all interior angles in a regular n-gon is (n-2) * 180 degrees, and all angles are equal in a regular n-gon.

Now, let's find the measure of angle W:

In triangle BAC:
- Angle BAC = (n-2) * 180 / n degrees, as explained above.
- Angle WAB = Angle WAC = (180 - Angle BAC) / 2 degrees. This is because triangle BAC is isosceles, and the base angles are equal.

Since angle WAB and angle WAC are equal, we can denote them as x degrees each.

Therefore, the measure of angle W is 2x degrees.

To find x, we can use the equation:
x + x + (n-2) * 180 / n = 180 degrees
(2x + (n-2) * 180 / n) = 180 degrees

Simplifying the equation, we get:
2x + (n-2) * 180 / n = 180 degrees
2x = 180 - (n-2) * 180 / n
2x = (n * 180 - (n-2) * 180) / n
2x = (n * 180 - 180n + 360) / n
2x = (360 - 180n + 360) / n
2x = (720 - 180n) / n
x = (720 - 180n) / (2n)
x = 360/n - 90

Finally, the measure of angle W is
2x = 2(360/n - 90)
= 720/n - 180

So, the measure of angle W in terms of n is 720/n - 180 degrees.
