he pentagon ABCDE is graphed on a coordinate plane with vertices A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0). What is the pentagon's perimeter?
A) 27.6 units
B) 16.0 units
C) 32.4 units
D) 24.0 units
Answers
Answer:
I think the coordnates are incorrect because they do not make a pentagon when graphed. Could you please check and make sure those are right.
Step-by-step explanation:
But to do the question, you graph the points and then use the distance formula to find the side lengh of each side. Then simply just add them together. Also if you don't want to draw out a coordnate plane, you can use Desmos, an online graphing calculator.

D. Is the data skewed? If so, is it skewed right or skewed left? (Answer Left or Right or Not Skewed)
Answers
Answer:
Data set = 12,14,28,28,30,30,32,32,32,32,34,34,34,36,36,36,36,36,38,38
A.) Median
B.) Median = 33
C.) Yes, Outliers: 12 and 14
D.) Skewed left
Step-by-step explanation:
Outliers: Points in the data set that are either way too small or way too big than other numbers in the data set.
Skewed: A sudden change in the data set going away from the data set:
Skewed right: If most of the data are on the left side of the histogram but a few larger values are on the right, the data are said to be skewed to the right.
Skewed left: If most of the data are on the right, with a few smaller values showing up on the left side of the histogram, the data are skewed to the left.
Not Skewed: If the data are symmetric, they have about the same shape on either side of the middle.

1. Two of the angles of a triangle measure 15° and 150°. Classify the triangle.
A. Equilateral
B. Scalene
C. Isosceles
Answers
Its Isosceles
cause a triangle must always add up to 180 if you are finding the angles and they give you 15 and 150 if you add that you get 165 and i you subtract that from 180 you get 15 and a isosceles has 2 equal angles
Answer:
Isosceles
Step-by-step explanation:
An isosceles triangle is a triangle with two equal sides, as well as two equal angles. So take 150, add it to 15. You get 165. Take 180, then subtract 165. You get 15, and since you know another angle is 15, you have an isosceles triangle.

5.The measure of smaller angle is 87 degrees.
Step-by-step explanation:
Consider the provided information.
The provided angles are 3x degree and 2x + 25 degree.
Two angles are said to be Supplementary angles if their sum is 180 degree.
It is given that the provided angle are supplementary angles, thus
3x + 2x + 25 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 31
Now, substitute the value of x in first angle i.e 3x.
3(31) = 93
Substitute the value of x in the second angle i.e 2x + 25
2(31) + 25 = 62 + 25 = 87
Hence, the measure of smaller angle is 87 degrees.

4,712 yards.
We can use the formula V=1/3hπr² to figure out what the volume of the cone is.
So using the numbers provided the new equation would be V=1/3(20)π15², which would come out to 4,712 yards.

Find the missing side. Round to the nearest tenth when necessary.
Answers
Answer:
15.6
Step-by-step explanation:
Because it is a right triangle, you can use the Pythagorean Theorem. The theorem is c^2 = a^2 + b^2, with c being the hypotenuse, and a and b being the legs. So plug in the values and you will get 18^2=9^2 + b^2. Solve for b and you will get 15.6.
Answer:
x=15.59
Step-by-step explanation:
using the pythagorean theorem we know a²+b²=c²
also that c²-a²=b². in this case we're using the second one. c² is 18², and a² is 9². 18²-9² is 243. we then find the square root of that number to get x (b²). x=15.59 rounded to the nearest hundreth.
