Explanation:
Angle 3 and the 100 degree angle are corresponding angles. They are both in the southeast quadrant of their four-corner angle configuration. Assuming the lines that look horizontal are parallel, this would mean angle 3 is 100 degrees. Recall that corresponding angles are congruent when we have parallel lines.
Once we know that angle 3 = 100, we will use this to find angle 4.
Angles 3 and 4 add to 180. They form a straight angle or straight line.
(angle3)+(angle4) = 180
(100) + (angle4) = 180
angle4 = 180-100
angle4 = 80 degrees
because angle 4=angle8 and since angle 8+ 100degrees= a straight line (180 degrees) angle 4=80

A pentagon has 3 congruent sides and 2 other congruent sides. The perimeter of the pentagon is 36 centimeters. The three long congruent sides are 2 centimeters longer than the two shorter congruent sides.
Let x = length of a short side
Let y = length of a long side
The system of equations can be used to represent the situation.
y = x + 2
2x + 3y = 36
What is the length of one of the shorter congruent sides?
Answers
Answer:
Length of one of the shorter congruent side is: 6 cm
Step-by-step explanation:
In order to find the length of congruent sides we have to solve the system of equations
Given systems of equation is:
y = x + 2
2x + 3y = 36
Putting y = x+2 in second equation
[tex]2x + 3(x+2) = 36\\2x+3x+6 = 36\\5x+6 = 36\\5x = 36-6\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x =6[/tex]
As we know that x represents the shorter side, the length of short side is: 6 cm
Hence,
Length of one of the shorter congruent side is: 6 cm

Find the value of f(-6).
Answers
Answer:
f(-6) = 5
Step-by-step explanation:
We want to find the value of the graph when x = -6
Go to where x = -6 and the y value is 5
f(-6) = 5
The number inside f(-6) is just x. So, use your finger to find -6 on the x-axis. Then, trace your finger in a vertical line to find where the function crosses where x = -6. This will be f(-6). We can see that this is 5.

A square field has an area of 479² ft What is the approximate length of a side of the field? Give your answer to the nearest foot. Explain your response.
Answers
Answer:
≈ 22 ft
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( where s is the side length )
Given A = 479, then
s² = 479 ( take the square root of both sides )
s = [tex]\sqrt{479}[/tex] ≈ 22 ft ( to the nearest foot )
Answer:
A = 479 sq ft
479 = x²
square root of 479 = square root of x²
21.89 = x
rounded= 22 ft

Answer:
A) Scale factor from A to B is 2
B) Length of left side is 3 and length of right side is 5.
Step-by-step explanation:
A) Length of the top side is 2.5 in A and is 5 in polygon B. 5/2.5 = 2, therefore scale factor is 2.
B) Because the scale factor is 2, each of the sides double while the angles stay the same. Therefore, the length of the side on the left is 3 and length of the side on the right is 5.
1.5 x 2 = 3
2.5 x 2 = 5
Part (a)
Divide the upper horizontal lengths of the two figures:
5/2.5 = 2
The scale factor is 2. This means figure B has side lengths twice as long compared to figure A.
Answer: Scale factor = 2=======================================================
Part (b)
The missing side length seems to be the diagonal side of figure B. I'm not sure what's going on with the vertical side 89.4 as that should be 3 instead (since 1.5*2 = 3).
The diagonal side is 5 units long since we double 2.5 to get 5.
Answers:
vertical side = 3
diagonal side = 5

All tickets to a play have the same cost. A group bought 6 tickets and paid a total of $99. Write a multiplication equation that can be used to determine cost c in dollars for each ticket.
Answers
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The multiplication equation to determine the cost C in dollars of each ticket is C = 99 x 1/6.
The cost of each ticket is $16.5.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
6 miles in 2 hours
0ne hour will be 3 miles.
We have,
6 tickets = $99
Divide both sides by 6.
1 ticket = 99/6
1 ticket = $16.5
The multiplication equation to determine the cost C in dollars of each ticket:
$C = 99 x 1/6
Thus,
The multiplication equation to determine the cost C in dollars of each ticket is C = 99 x 1/6.
The cost of each ticket is $16.5.
