Complete the missing parts of the paragraph proof. We know that triangle DFE is isosceles with base FE and that segment FB is congruent to segment EC because . Segment DF is congruent to segment by the definition of isosceles triangle. Since these segments are congruent, the base angles, angles , are congruent by the isosceles triangle theorem.

Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 6 units long. Point C is on the line x = −3. If the area of ΔABC is 9 square units, then find a possible y-coordinate of point C.
5
6
7
8
Answers
Answer:
y-coordinate is 5 or -1.
Step-by-step explanation:
Point A is at (x, 2) and B is at (x+6, 2). Since AB must lie on the line y=2 and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).
Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).
The area of ΔABC is 6. So,
9 = 1/2 (b)(h)
where b is the base and h is the height.
so b = 6 and h = AC
Solving this for C gives
9 = 1/2 (6)(AC)
18/6 = AC
3 = AC
9 = 1/2 (6)(AC)
18/6 = AC
3 = AC
Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.
If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.
Therefore, y-coordinate is 5 or -1.

Answer:
x = 48 degrees
Step-by-step explanation:
Total internal angles:
180 degrees * 3
= 540 degrees
540-105-102-93
= 240
240 = 5x
x = 48
PLS GIVE BRAINLIEST
Answer:
2x = 96º
3x = 144º
Step-by-step explanation:
sum of all angles ina pentagon is 540, so:
2x+3x+105+93+102 = 540
5x+ 300 = 540
5x = 540-300
5x = 240
x = 240/5
x = 48
3x = 48.3
3x = 144
2x = 48.2
2x = 96
proof:
105+93+102+144+96 = 540

Complete question :
Room temperature ranges from 20 degrees Celsius to 25 degrees Celcius. Find the range of room temperature in degrees Fahrenheit. Use the formula F-32=1.8C to convert from the Celsius scale to the Fahrenheit scale
Answer:
68°F to 77°F
Step-by-step explanation:
Given that:
Temperature range in degree celcius :
20°C to 25°C
The temperature range in degree Fahrenheit is :
Using the relation :
F-32=1.8C
20°C :
F-32=1.8(20)
F = 36 + 32
F = 68°
25°C :
F-32=1.8(25)
F = 45 + 32
F = 77°
Hence, range of room temperature in Fahrenheit scale is :
68°F to 77°F

City X would have summer at position 4.
The image shows the rotation of the earth around the sun and a city in the northern hemisphere is marked with a letter X.
In the positions shown on the earth the stations are:
position 1 would be autumn in the northern hemisphere and spring in the southern hemisphereposition 2 would be winter in the northern hemisphere and summer in the southern hemisphere.position 3 would be spring in the northern hemisphere and autumn in the southern hemisphere.Position 4 would be summer in the northern hemisphere and winter in the southern hemisphere.The distribution of the seasons originates from the position of the earth concerning the sun and the areas most exposed to solar rays, as can be seen in position 4, the northern hemisphere is more exposed to solar rays, while the south is less exposed.
According to the above, the correct answer is 4. In this position, the north is in summer and the south in winter.

What is 6(x-6)=x(16-7) as well as the steps?
Answers
Answer:
x = -12
Step-by-step explanation:
6x - 36 = 9x
-36 = 3x
3x = -36
x = -12
Answer:
x = -12
Step-by-step explanation:
6(x-6) = x(16-7) given
6x - 36 = 16x -7x distributive multiplication
6x - 36 = 9x simplify
-3x - 36 = 0 subtract 9x to both sides of equality
-3x = 36 add 36 to both sides of equality
x = -12 divide by -3 to both sides of equality

Juan is making a cookout and needs 5 kilograms of fajita. There are approxiently 450gras in 1 pound. Which measurement is closest to the number of pounds in 5 kilograms
Answers
Answer:
The measurement closest to the number of pounds in 5 kilograms is 11.1 pounds
Step-by-step explanation:
To determine the measurement closest to the number of pounds in 5 kilograms,
First, we will convert 5 kilograms to grams. Let the value in grams be x grams.
(NOTE: 1 kilogram = 1000 grams)
If 1 kilogram = 1000 grams
Then, 5 kilograms = x grams
x = (5 × 1000) / 1 grams = 5000 grams
∴ 5 kilograms = 5000 grams
Now, we will determine the measurement closest to the number of pounds in 5000 grams. Let the number of pounds in 5000 grams be y.
From the question,
There are approximately 450grams in 1 pound
If there are 450 grams in 1 pound
Then, there will be 5000 grams in y pounds
y = (5000 × 1) / 450 pounds = 11.1 pounds
y = 11.1 pounds
∴ 5 kilograms = 5000 grams = 11.1 pounds
Hence, the measurement closest to the number of pounds in 5 kilograms is 11.1 pounds.
