If you are given the measure of each interior angle (162 degrees) of a regular polygon. how many sides does the polygon have? If you look at a pentagon first where the interior angle is 108 deg then you see. The angle at the center is 180-162=18 deg and 360/18=20 so the polygon has 20 sides.
Hope this helps you !!
Answer:
The shadow length is 125 inches.
Step-by-step explanation:
The triangle that the sun's rays and the fence post form is shown in the figure.
From trigonometry we know that 
is the ratio of the opposite <em>(72-in fence)</em> to the adjacent side 
of the triangle <em>(the shadow length): </em>
<em />
<em />
since
<em />
<em />
we have
<em />
<em />
solving for we get:
Hence, the length of the shadow to the nearest inch is 125 inches.
Answer:
C = 17 - R
Step-by-step explanation:
In this scenario, 17 cars would be the initial starting point. While C would be the final number of cars, meaning that our equation would have to equal C. If she rents R number of cars then this number is being subtracted from the initial number of cars because Charmaine would no longer have them in his/her possession. Therefore, it is being subtracted. Using this information we can create the following equation.
C = 17 - R
Answer:
(-2, 3)
Step-by-step explanation:
To find the difference between two pairs of points, use the slope formula of M = (y2-y1) over (x2-x1). This gives you ( 3/-2 ) with the top number being Y and bottom number being X.
