Answer:
B = 18
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
D = B+C
117 = 8x+27 + B
Angle A and angle B are supplementary, which means they from a straight line. They add to 180 degrees
<A + <B = 180
18x + <B = 180
Solving for B
B = 180 -18x
Putting this into the above equation
117 = 8x+27 + 180-18x
Combing like terms
117 = 207-10x
Subtract 207 from each side
117-207 = 207-207 -10x
-90 = -10x
Divide by -10
-90/-10 = -10x/-10
9= x
We need to find angle B
B = 180 -18x
= 180 - 18(9)
= 180 -162
= 18
I'm guessing you're asking for the length and width.
Width: 5
Length: 13
l=5(2)+3
l=10+3
l=13
A pie chart organizes information depending on what your asking.
For instance,
there are 100 people living in an area.
The question is, what percentage of those people own a cat, dog, bird, fish, and other.
After gathering the results, it seems that,
30% have dogs
25% have cats
15% have birds
10% have fishes
20% have other pets
These results are what were given. And if u put this in a pie chart, you can see that most of those 100 people own dogs while least amount of people own fish. Also, if u add up all the percentages, it makes 100% which is anyways mandatory when making a pie chart, so always count them.
I hope this helps!!
please make my answer brainliest!!
Thank you so much!!
Answer:
yes it is
Step-by-step explanation:
Ur graph.....u have a line that has a y int of -2....it has a slope of 3....it has a solid line...so there is no equal sign...it is shaded above the line, so it is greater then.....y > = 3x - 2
u have another line that has a y int of 2....it has a slope of -1/2....it has a solid line...so there is an equal sign in the problem...it is shaded below the line...so it is less then....
y < = -1/2x + 2
1/2x + y < = 2...multiply by 2
x + 2y < = 4
so ur answer is : y > = 3x - 2 and x + 2y < = 4...the 2nd one
