Answer:
Divide the measurement by 36 to determine the number of yards needed. For example, if the pattern pieces cover an area of floor equal to 72 inches in length, then divide 72 by 36 to get 2, the number of yards of 54-inch wide fabric needed for the ottoman.
Answer:
Option D.75°
Step-by-step explanation:
we know that
The sum of the interior angles of a regular dodecagon is equal to

where
n is the number of sides
In this problem
n=12 sides
substitute


Find the measure of each interior angle
Divide the sum of the interior angles by the number of sides

The measure of the angle formed by the radius and the side of a regular dodecagon is half the measure of the interior angle
therefore

It is 62.54
Hope this helped.
Since the pentagon is regular, the sides are all of equal length. This tells you
... 5x-27 = 2x-6
... 3x = 21 . . . . . . . add 27-2x
... x = 7
The length of a side can be found by subtituting this value into either expression.
... 2·7-6 = 8 . . . . inches
