The length of AC is congruent to WY
d = 10
<span>1/5
This is a matter of elimination. So let's figure out how many of each display there is.
30% of 150 = 0.30 * 150 = 45 displays about electricity.
2/5 * 150 = 0.40 * 150 = 60 displays about renewable energy
1/10 * 150 = 150/10 = 15 displays about gas.
The rest of the displays are about nuclear power. So
150 - 45 - 60 - 15 = 30 displays about nuclear power. Since we want a fraction, we get 30/150
But 30/150 isn't in it's simplest form. The largest number that will evenly divide both 30 and 150 is 30. So divide both the numerator and denominator by 30
(30/30)/(150/30) = 1/5
So 1/5 of the displays are about nuclear power.</span>

Answer:
<u>The regular polygon has 13 sides</u>
Correct statement and question:
If the sum of the measures of the interior angles of a polygon is 1980°, how many sides does it have?
Source:
1,920° is not a valid value for a regular polygon. It should be either 1,980° or 1,800° (it has to be a multiple of 180). We pick 1,980° to answer the question.
Step-by-step explanation:
Let's recall that the formula of the sum of the interior angles of any polygon is:
Sum of Interior Angles = (n-2) * 180°, where n is the number of sides of the polygon.
Therefore, replacing with the value we know:
1,980 = (n-2) * 180
n - 2 = 1,980/180
n - 2 = 11
<u>n = 13</u>
