Which of the following proves these triangles are congruent?
Explanation:
ASA = angle side angle
It refers to knowing two pairs of congruent angles, and a pair of congruent sides between the angles.
The angle markers tell us which angles are congruent. The shared overlapped sides are congruent (since any segment is congruent to itself; aka reflexive property).
ASA is slightly different from AAS in that the congruent sides for AAS are not between the congruent angles.

If the perimeter of the square is 48 m. Find the area of a
circle whose circumference is the same as the square.
The area of the circle is 201 m².
What is a circle?All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.So, the area of the circle:
The perimeter of square: 4aCircumference of the circle: 2πrWe know that 4a = 2πr, now calculate r as follows:
4a = 2πr48 = 2πrr = 48/2πr = 48/2(3.14)r = 48/6.28r = 7.64Rounding off: 8m

If the temperature drops 5 degrees per hour , what is the change in temperature after 4 hours
Answer: -20 degrees
Step-by-step explanation:
The temperature drops 5 degrees/hour.
Find temperature after 4 hours.
Since we are not given a starting temperature, we can only say how much the temperature has dropped after the 4 hours.
5 degrees/hour x 4 hours = 20 degrees
Temperature has dropped so your answer will be negative.

Answer:
area: 1641.6 square inchesperimeter: 168.8 inchesStep-by-step explanation:
You want the area and perimeter of a rectangle that is 54 inches in length and 30.4 inches in width.
AreaThe area formula is ...
A = bh
We can use the length as the "base" and the width as the "height", so we have ...
A = (54 in)(30.4 in) = 1641.6 in²
The area of the television screen is 1641.6 square inches.
PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Using the given length and width, the perimeter is found to be ...
P = 2(54 in + 30.4 in) = 2(84.4 in) = 168.8 in
The perimeter of the television screen is 168.8 inches.
The area of the rectangular television screen is 1641.6 square inches and the perimeter of the television screen is 84.4 inches.
What is the area of a rectangle?
The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the product of its length and breadth. Its area is the space that the rectangle's boundary encloses.
Mathematically, area of a rectangle = length * width = l * w
What is the perimeter of a rectangle?
The perimeter is defined as the sum of all sides of the rectangle. Mathematically, perimeter of a rectangle = 2(length + width) = 2*(l + w)
Given, the length of the television screen = l = 54 inches
The width of the television screen = w = 30.4 inches
Using the formula mentioned in the literature above,
Area of the television screen = l * w = 54*30.4 = 1641.6 square inches
Also, perimeter of the television screen = l + w = 54 + 30.4 = 84.4 inches
Thus, the area of the rectangular television screen is 1641.6 square inches and the perimeter of the television screen is 84.4 inches.

Step-by-step explanation:
For a project in his Geometry class, Yusuf uses a mirror on the ground to measure the
height of his school building. He walks a distance of 10.25 meters from the building,
then places a mirror flat on the ground, marked with an X at the center. He then
walks 1.65 more meters past the mirror, so that when he turns around and looks
down at the mirror, he can see the top of the school clearly marked in the X. His
partner measures the distance from his eyes to the ground to be 1.55 meters. How tall
is the school? Round your answer to the nearest hundredth of a meter.
Step-by-step explanation:
sadly we don't know anything about the size of the mirror on the ground, or if e.g. the 1.65 m from the mirror mean from the edge of the mirror or from the x at the center of the mirror.
so, we must assume the mirror as a dot without any significant lengths in the calculation.
we have 2 right-angled triangles.
1. the small one : from Yusuf's eyes to the ground at his feet to the x on the mirror on the ground.
2. the large one : from the top of the building to the bottom of the building on the ground to the x on the mirror on the ground.
the mirroring creates a dilation from the large triangle to the small triangle through the point x on the mirror.
in other words, all the angles stay the same, and there is one constant scale factor for all the lengths of one triangle to the other, making both triangles similar.
that means that the scale factor "f" of the ground distances from the small to the large triangle is
10.25 / 1.65 = 1025 / 165 = 6 35/165 = 6 7/33 =
= 6.212121212...
the scaling from Yusuf's height (well, his eye level) to the height of the school must follow the same ratio :
school height / Yusuf's eye level =
= h/1.55 = 10.25/1.65
h = 10.25 × 1.55 / 1.65 = 1025 × 155 / 16500 =
= 9.628787879... m ≈ 9.63 m
the school is approximately 9.63 m tall.
FYI : this is the same principle as with a camera. the lens (and the mirror inside if applicable) create a dilated "projection" onto a film or an array of digital light sensors, so that the captured image retains all the angles and all the length ratios of the original.
but to know from the picture e.g. how tall the original was, we need to know also the distance from which the picture was taken. otherwise this can't be answered.

Write the perimeter of the triangle as a simplified polynomial. Then factor the polynomial.
Answer:
4x² + 29x + 7 = (4x + 1)(x + 7)
Step-by-step explanation:
Simplify the polynomial:Like terms are terms with same variable and same power.
Perimeter = sum of all the sides
= 3x² + 1 + 15x + 6 + x² + 14x
= 3x² + x² + 15x + 14x + 1 + 6
Combine like terms,
= 4x² + 29x + 7
Factorize:
Sum = 29
Product = 4*7 = 28
Factors = 1 , 28 {28 + 1 = 29 & 28*1 = 28}
Rewrite the middle term using the factors,
= 4x² + x + 28x + 7
= x(4x + 1) + 7(4x + 1)
= (4x + 1)(x + 7)

Answer:
D
Step-by-step explanation:
Look at the original figure that is complete. The left side of the figure has a length of 3 units, the top of the figure has a length of 2 units and the bottom of the figure has a length of 3 units.
If you multiply each of those lengths, you will have 9 (3x3), 6 (2x3) and 9 (3x3). Do you see in the large figure to the right, that you have a left side of 9, a top of 6 and a bottom of 9? That is what you original figure looks like if we multiply the sides by 3. We are missing the right side point. That is the point on the right side that points inward.
If you look at the original shape and start at the left had bottom corner, you would have to move up one and one to the right to plot the point to finish the figure. So, for the new figure we would need to go up three and three to the right to put the last point. That would be point D.
solve for s 1.1=s+2.3/3
Answer:
s=1Step-by-step explanation:
Find the value of s on one side of the equation to isolate it.
1.1=s+2.3/3
First, switch sides.
[tex]\sf{\dfrac{s+2.3}{3}=1.1}[/tex]
Multiply by 3 from both sides.
[tex]\sf{\dfrac{3\left(s+2.3\right)}{3}=1.1* \:3}[/tex]
Solve.
1.1*3=3.3
s+2.3=3.3
Then, subtract by 2.3 from both sides.
s+2.3-2.3=3.3-2.3
Solve.
Subtract.
3.3-2.3=1.0=1
s=1
Therefore, the final answer is s=1.
