Given: 21 and 22 are supplementary, and 22 and 23 are supplementary.
Prove: 21223
By definition of supplementary angles, m_1 = m22 = (a) and m22 - mz3 = (6)
Then, m_1 - m42 = m_2 + m23 by the

The complete paragraph proof is explained below.
What are supplementary angles?Two or more given angles are said to be supplementary when on adding there individual measure, it produce the sum of angles on a straight line i.e. 180^o.
To complete the paragraph proof, we have;
m<1 + m< = 180^o (definition of supplementary angles)
m<2 - m<3 = m<2 - m<1
m<1 + m<2 = m<2 + m<3 (by the addition property of supplementary angles)
subtract m<2 from each side,
m<1 + m<2 - m<2 = m<2 + m<3 - m<2
you will get;
m<1 = m<3
Therefore, m<1 ≅ m<3

8 ft 7 in. = in.
Ayudaaa help
Answer:
103 inches
Step-by-step explanation:
So, Since we know that 12 in = 1 foot
all we have to do is multiply 12 by 8. Think of it like: what will 8 sets of 12 blocks give us?
8 x 12 = 96
So, 8 feet is 96 inches.
Now, Just add the 7 inches into the 96 inches.
96+7 = 103 inches
and then you are done!

In a certain chemical, the ratio of zinc to copper is 3 to 19. A jar of the chemical contains 494 grams of copper. How many grams of zinc does it contain?
enter your response here
It contains grams of zinc.
Answer:
3216 grams of Zn
Step-by-step explanation:
It is not clear from the question if the ratio is based on the chemical formula, and is thus the ratio of atoms, or if it is based on mass (in g). I'll assume it is based on the numbers of Zn and Cu atoms.
Let's convert the mass of copper, 494 grams, to moles of copper (representative of the number of atoms). The molar mass of copper, Cu, is 63.55 grams/mole.
Moles Cu =(494 grams)/(63.55 grams/mole) = 7.77 moles Cu
If zinc (Zn) is in a ratio of 19/3, we would have:
(19 moles Zn/3 moles Cu)*(7.77 moles Cu) = 49.2 moles of Zn
The molar mass of zinc is 65.38 grams/mole
The mass of 49.2 moles of Zn is:
(49.2 moles Zn)(65.38 grams/mole) = 3216 grams of Zn

The function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an airplane to travel west. Given f(x) = 4x 13 and g(x) = 10x − 2, solve for (f g)(x) to determine the total roundtrip time. (f g)(x) = 14x 15 (f g)(x) = 14x 11 (f g)(x) = 6x 11 (f g)(x) = 6x 15.
The total time taken for round trip will be (f+g)(x) = 14x+11
We have given that
f(x)=4x+13and g(x)=10x-2
What is the round trip time?In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.
Therefore we get,
[tex](f+g)(x)=f(x)+g(x)\\ =(4x+13)(10x-3)\\ =4x+13+10x-2\\ =4x+10x+13-2\\ =14x+11[/tex]
Hence,The total time taken for round trip will be: (f+g)(x) = 14x+11

An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Let one angle be x
Other angle =x + 82
Complementary angles add up to 90
x + x + 82 = 90
2x + 82 = 90
2x = 90 - 82
2x = 8
x = 8/2
x = 4
Other angle = x + 82
= 4 +82
= 86
The angles are: 4 , 86
An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?
❖ Explanation -:Given -:
An angle measures 82º more than the measure of its complementary angle.Need to find -:
Measure of each angleAssuming -:
An angle measures 82º more than the measure of its complementary angle.
Let us assume one angle as x
Then other angle = (x + 82)
Solution -:
First we will make an equation
We know,
Complementary angles add up to 90°
x + (x + 82°) = 90°
→ x + x + 82° = 90°
→ 2x + 82° = 90°
→ 2x = 90° - 82°
→ 2x = 8
→ x = [tex]\cancel{\dfrac{8}{2}}[/tex]
→ x = 4
Substituting the value of x = 4
One angle = x = 4°
Other angle = x + 82° = (4 + 82)° = 86°
Final Answer -:
The angles are 4 and 86.[tex] \rule{180pt}{2pt}[/tex]
