Answer:
2340°
Step-by-step explanation:
To find the sum of interior angles of any shape, use the formula: 180(n - 2), where <em>n</em> is how many sides there are. <em>So</em>,
180(15 - 2)
180(13)
2340
The area of a plot is the amount of space on the plot
The area of the plot is 2x^2 -x - 1
<h3>How to determine the area</h3>
The dimensions of the plot are given as:
Length=2x+1
Width=x-1.
The area of the plot is the product of its dimension.
So, we have:
Expand
Evaluate the like terms
Hence, the area of the plot is 2x^2 -x - 1

Answer:
-28 = x
Step-by-step explanation
[5x + 20] + [4x - 8] = 180
9x + 12 = 180
- 12 -12
______________
9x = 168
18⅔ = x
m∠EBC = 5[18⅔] + 20 = 113⅓
93⅓
You will get a negative answer if you set them equal to each other, which is not allowed when you are talking about <em>length</em><em>.</em>
I hope this is correct, and as always, I am joyous to assist anyone at any time.
