Find the area A of polygon CDEFGH with the given vertices. C(0,5), D(2,5), E(2,3), F(3,2), G(-1,2), H(0,3)
enot [183]
Answer:
<em>The area of the polygon CDEFGH is 7</em>
Step-by-step explanation:
<u>Area of a Polygon</u>
The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.
The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:
The area CDHE is a square of length side 2. Area of a square:

The area HEFG is a trapezoid with bases lengths 4 and 2, and height 1. Area of a trapezoid:

Calculate both areas:


Total Area=4+3=7
The area of the polygon CDEFGH is 7
Answer:
18
Step-by-step explanation:
Mode = modal class (Recurring)
The number/value that appears the most which in this case is 18 because it can be seen twice.
I believe 4 sorry if I'm wrong
In a kite, all of the angles added together equal 360. You already know there are two right angles, and because of this, you would subtract 180 from the 360, leaving you with 180. In order to solve for x, you have to add 18x-2 to 12x+2 and set it equal to 180. Your equation would be 18x - 2 + 12x + 2 = 180. The 2's would cancel out, leaving you with 18x + 12x = 180, 30x = 180, then 6 = x.
