Answer:

angle2=23°

angle7=angle5

angle2=angle6

so,angle8=23°

total angle = 180°

angle7=180°-46°=134°÷2=67°

Using corresponding angles are equal property we found that m∠7 = 157°

When two parallel lines are intersected by an transversal line then the pair of angles formed on one same side of transversal on both parallel lines are corresponding angles. As in the figure attached ∠ 1 and ∠5 are  corresponding angles.∠4 and ∠8 are also corresponding angles.

Corresponding angles are always equal.

Given that x and y are parallel lines.

Then ∠2 and ∠6 are corresponding angles , therefore m ∠2 = m ∠6

Given that m∠2 = 23°

⇒ m∠6 = 23°

As ∠7 and ∠6 are on same line hence they are supplementary

m∠7  + m∠6 = 180°

⇒m∠7 + 23° =180°

⇒m∠7  =180°- 23° = 157°

Therefore, the measure of angle ∠7 is 157°

AB || CD and AC is oblique ;

So : Angle ( BAC ) = Angle ( DCA )

_________________________________

∆ ABC - ∆ ACD :

(1) AB = CD

(2) Angle ( BAC ) = Angle ( DCA )

(3) AC = AC

So According to (1) , (2) , (3) :

∆ ABC =~ ∆ ACD

Well, if two triangles are deposited, all their components are equal peer to peer.

Answer:

A

Step-by-step explanation:

6 friends

Mean - 10

Median - 9.5

Range - 14

3 friends watched 12, 13, and 18 movies.

Let's find the sum, this will help us find the total number of movies the other 3 friends watched.

12 + 13 + 18 = 43

The mean is all their movies added toether, divided by the number of friends.

m = number of movies the other friends watched.

(43 + m) / 6 = 10        Multiply each side by 6

43 + m = 10 * 6

43 + m = 60          Subtract 43 from each side

m = 60 - 43

m = 17

So we know the total movies the other friends watched is 3.

A. 4+6+7 = 17

B. 4+4+7 = 15

C. 5+8+9 = 22

D. 2+3+5 = 10

We know the answer is A.

We can check it by looking at the Median, the median is the middle number, if there are an even number of samples, you add the 2 middle numbers together and divide by 2.

4, 6, 7, 12, 13, 18

So 7+12 = 19

19/2 = 9.5

So we know for sure A is correct!

Answer:

TAG is described as an acute angle.

Step-by-step explanation:

This is because TAG is an angle that is less than 90 degrees.

Answer:

acute

Step-by-step explanation:

TAG

think of the angle, the gap is small and T is close to G

if it would be right the T would be upright

if it was straight T would lay flat corresponding to G making a line

if it was obtuse the gap would surpass the right angle outward

Answer:

12, 13, 14

Step-by-step explanation:

Three consecutive numbers means three numbers in a row, so if n is the first number, the second number is one more than  n (which is n+1) and the third number is one more than that (which is n+2)

So three times (3 x) the first number (n) is equal to (=) nine more than (9 +) the sum of the other two ( (n+1) + (n+2) )

3 times n can be written as 3n

So 3n = 9 + (n+1) + (n+2)

3n = 9 + n + 1 + n + 2

3n = 9 + 1 + 2 + n + n

3n = 12 + 2n

Subtract 2n from each side

3n - 2n = 12 + 2n - 2n

1n = 12

n = 12

So the first number is 12, the second number is 12 + 1 (13) and the third number is 12 + 2 (14)

The numbers are 12, 13, 14

Answerer: Darrell has already donated $23 to the foundation, so f (0) =$23.

Because x represents the number of weeks, and Darrell is contributing $1 every day, Monday through Friday, he will contribute a total of $5 per week. So, the total amount donated will increase by $5 each week. Therefore, the recursive function will be f (x) =f(x - 1) + $5, where f ($23).

The insulation fee for 175 square feet of carpet is $237.

Step-by-step explanation:

The amount of money, f(x), that it cost to purchase x square feet of the carpet is:

f(x)= 8x

The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have

g(x)=8% of f(x)+125

[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]

[tex]\Rightarrow=0.64x+125[/tex]

The insulation fee for 175 square feet of carpet,

i.e for x=175

[tex]g(x=175)=0.64\times175+125=237[/tex]

Hence, the insulation fee for 175 square feet of carpet is $237.

Answer:

m = 0

Step-by-step explanation:

To find the slope of a line, use the equation:

m = y2 - y1 / x2 - x1

Then, substitute in numbers:

m = 0 - 0 / -6 - 4

m = 0 / -10

m = 0

Therefore, the slope of the line is 0, meaning it has zero slope.

Answer:

-11

Step-by-step explanation:

-1/2y=1/2+5

- 1/2 y = 1+10 (by taking lcm)

               2  

 [tex]\frac{-1}{2}[/tex] x 2y = 11

y = -11

[tex] \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{11}{2} [/tex]

[tex]y = \frac{11}{2} \div \frac{ - 1}{ \: \: \:2} [/tex]

[tex]y = \frac{11}{2} \times \frac{ \: \: \: 2}{ - 1} [/tex]

[tex]y = \frac{ \: \: 22}{ - 2} [/tex]

[tex]y = - 11[/tex]

The value of y = -11

Therefore :-

[tex] \frac{ - 1}{ \: \: \:2} \times - 11 = \frac{1}{2} + 5[/tex]
