Answer:
Angles 2 and 6 are congruent as corresponding angles
Angles 6 and 7 form a linear pair.
Angles 2 and 6 are congruent as corresponding angles; angles 6 and 7 form a linear pair thus 2 and 7 will be supplementary angles so option (B) will be correct.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In the given figure lines m and n is parallel.
So,
Angle 2 = Angle 6 (Congruent)
Now,
Angle 6 and 7 are on a straight line so they will be linear pairs.
∠2 + ∠3 = 180
∠6 + ∠7 = 180
So,
(∠2 + ∠3) + (∠6 + ∠7) = 360
(∠2 + ∠7) + (∠3 + ∠6) = 180 + 180
Each corresponding pair will be the same because of congruent.
So,
(∠2 + ∠7) = 180
Hence "Angles 2 and 6 are congruent as corresponding angles; angles 6 and 7 form a linear pair thus 2 and 7 will be supplementary angles".

Katarina asks Dacia how she can you derive the formula r= x2+y2. Which of Dacia's replies are correct?
Options A and B are correct. If Katarina asks Dacia how she can derive the formula r= x²+y², then the following statements should be Dacia's reply.
Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'rr is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1Given the equation by Katarina expressed as:
r = √x²+y²
One of the ways Katarina can derive the equation is to use the Pythagoras theorem which states that the sum of the square of the hypotenuse is equal to the sum of the other two sides. Let:
r be the length of the hypotenuse
x and y be the other two sides
According to the theorem:
r² = x² + y²
Take the square root of both sides
√r² = √x² + y²
r = √x² + y²
Also, Katarina can use the trigonometry identity. According to a right triangle where:
sinθ = y/r
Cosθ = x/r
According to trigonometry identity, sin²θ+cos²θ = 1
(y/r)² + (x/r)² = 1
y²/r² + x²/r² = 1
(y²+x²)/r² = 1
y²+x² = r²
Swap
r²=y²+x²
This shows that the first two options are correct.
Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'r
r is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1

You need to buy a carpet that measures 7.5 yards long and 5 yards wide and costs $49.50 per square yard. How much will the carpet for the room cost?
Answer:
$1,856.25
Explanation:
To find the square yards, multiply length and width
7.5 * 5 = 37.5
Then, since each square yard costs $49.50, multiply the square yards and the cost
37.5 * 49.50 = 1,856.25
Thus the answer is $1,856.25
The carpet for the room will cost $1,856.25.
This is the product of the unit cost per square yard multiplied by the area of the room.
The area of the room is = 37.5 square yards (Length x Width)
Length of the room = 7.5 yards
Width of the room = 5 yards
Therefore, the total area of the room = 37.5 square yards (7.5 x 5)
Thus, the total area of the room is 37.5 square yards and since each square yard costs $49.50, the total cost for buying the carpet will cost $1,856.25 ($49.50 x 37.5).

If the 102,619 residents of a city are divided into 57 equal groups, then some residents don’t fit into a group.
How many residents would be in a group?
How many residents would not fit into a group?
Hey there! Here is your answer:
102,600 would be in a group. 19 would not be in a group.
Step-by-step explanation:
We can figure this out by doing 102,619 divided by 57. This gives us:
1,800 R 19
Now we need to multiply 1800 by 57 to see how many residents there are:
1,800 x 57 = 102,600
Our remainder tells us how many residents would not fit into a group. Since our remainder is 19, 19 would not be in a group.

the distance between the base of the tree and the base of the building is:
please
my guess is "15m" is it correct ?
Explanation:
Apply the pythagorean theorem to find the missing side.
[tex]a^2 + b^2 = c^2\\\\x^2 + 20^2 = 25^2\\\\x^2 + 400 = 625\\\\x^2 = 625-400\\\\x^2 = 225\\\\x = \sqrt{225}\\\\x = 15[/tex]
The horizontal leg of the right triangle is 15 meters long. This is the distance from the base of the tree to the base of the building.
Side note: This right triangle is based off the 3-4-5 right triangle. It has been scaled up by a factor of 5.
Need Help!!!!!!!!!!!!!!Find the outer perimeter of this figure. Round your answer to the nearest hundredth.
Answer:
The perimeter of the figure is 14.71 ft
Step-by-step explanation:
The outer perimeter of the figure is the sum of the boundary dimensions.
The missing outer dimension is the length of the arc or half circumference.
Length of arc formula/half circumference = 1/2 πr = 1/2 x 3.14 x 3 ft = 4.71 ft
The other dimensions are 5ft and 5ft.
Therefore, the outer perimeter of the figure is:
4.71 ft + 5 ft + 5 ft = 14.71 ft

There are 80 cupcakes to be sold at school for a
fundraiser.
1/4 were chocolate
1/5 were vanilla
The rest were strawberry flavored. How many
cupcakes were strawberry flavored?
Answer:
44
Step-by-step explanation:
Let S = strawberry count
Chocolate = 1/4 * 80 = 20
Vanilla = 1/5 * 80 = 16
Total = C + V + S
80 = 20 + 16 + S
80 - 20 - 16 = S = 44
