please help me with this question

In engineering, equilateral triangles can support the most weight and so are commonly found in the design of bridges and buildings. Equilateral triangles are triangles with three congruent sides and three congruent angles. What are the measures of the angles of an equilateral triangle?​

Answer:

Parallel

Step-by-step explanation:

Let the required lines be y-x = 5 and y = x-1

If y-x = 5

y = x + 5

The slope m = 1

For the line y = x - 1

The slope m is also 1

Since the slope of both lines are the same, hence both liens are parallel

Answer:

The slope is 4

Step-by-step explanation:

basilly you add easy x(-1,-7) + y(3,9) = 2/2

make sure that you add x left and y right  first -1+3=2 and then -7+9=2 equal=2,2 together and just add both equal 4

Most easy just put you answer in a graht and count the squares

hope this helps ;)

Answer:

The three gallon container is the better buy. See below.

Step-by-step explanation:

8 pints

2 pints = 1 quart.

8 pints = 4 quarts.

4 quarts = 22.64   Divide by 4

1 quart = 5.66

3 gallons.

1 gallon = 4 quarts

3 gallons = 12 quarts.

The cost of 1 quart = 54.48/12 = 4.54

Answer:

46

Step-by-step explanation:

180-134=46

Answer:

They're both 46 degrees

Step-by-step explanation:

Angle b and 134 are right next to each other so they're supplementary and have to equal 180 degrees.

180-134=46, and since Angle c is is a vertical angle with Angle b, it also equals 46^^

Answer:

-4(3v - 10)(3v + 10)

Step-by-step explanation:

You must find the factored form of 400 - 36v^2.

You can rearrange this to - 36v^2 + 400 to make it less confusing.

So you have - 36v^2 + 400.

The next step is to see what you can take out of this. You can take out a GCF, a greatest common factor. This is basically a number that goes into both 36 and 400. This number is 4.

36 / 4 = 9 and 400 / 4 = 100.

Since it is a negative 36, you need to take out a negative 4.

So you put a 4 outside parenthesis and divide - 36 / 4 and 400 / 4.

-4(9v^2 - 100).

Now you must factor the inside of the parenthesis.

9v^2 - 100.

This is the same as 9v^2 + 0v - 100.

What are 2 numbers that multiply to get -100 and add to get 0?

These numbers are -10 and +10.

2 terms that multiply together get 9v^2 are 3v and 3v.

So the answer is:

-4(3v - 10)(3v + 10).

This is the factored form.

Answer:

5

Step-by-step explanation:

14+35=49 and we are looking for the number times 7 that gives us 49.

So, we already have 2. 2+ what times 7 gives us 49? 2 + 5 = 7 and so now our equation looks like this:

14+35 =7 (2+5)

Or

14+35= 7x7 becuase 7x7 is 49 and 14+35 is also 49.

Answer:

194

Step-by-step explanation:

Given:

Radius of the circle = 10 in

Central angle of the sector = 45 degrees

To find:

The area of the sector.

Solution:

Area of a sector is

[tex]A=\dfrac{\theta}{360^\circ}\pi r^2[/tex]

Where, [tex]\theta[/tex] is the central angle in degrees.

Putting r=10 and [tex]\theta=45^\circ[/tex], we get

[tex]A=\dfrac{45^\circ}{360^\circ}\pi (10)^2[/tex]

[tex]A=\dfrac{1}{8}\pi (100)[/tex]

[tex]A=12.5\pi[/tex]

Therefore, the area of the sector is 12.5π sq. inches.

Answer:

x² + 4x - 12

Step-by-step explanation:

(x+6)(x-2)

=> (x*x) + (x*-2) + (6*x) + (6*-2)

=> (x²) + (-2x) + (6x) + (-12)

=> x² - 2x + 6x - 12

=> x² + 4x - 12

So, once you simplify this equation the answer you should get is, x² + 4x - 12.

Hope this helps!

The pan radius is 4", and so the approximate area of the pan bottom is

A = pi(4 ")^2, or 16 pi, or 50 square inches.

Answer:

x = 51°

Step-by-step explanation:

The sum of all angles in a triangle is 180°.  (Angle Sum Property)

We already know 2 angles, the right angle and the 39°.

(x + 90 + 39)° = 180°

(x + 129)° = 180°

x = (180 - 129)°

x = 51°

Answer:

X=  70.5

Step-by-step explanation:

The area of a triangle is 180

180 - 39 = 141

141/2 = 70.5

70.5 + 70.5 + 39 = 180

Answer:

BC = 4.7

Step-by-step explanation:

From the question given above, the following data were:

Angle A = 21 °

Hypothenus = AC = 13

Opposite = BC =?

The length of BC can be obtained by using sine ratio as illustrated below:

Sine A = Opposite /Hypothenus

Sine 21 = BC / 13

0.3584 = BC / 13

Cross multiply

BC = 0.3584 × 13

BC = 4.7

Thus, the length of BC is 4.7

dont spread Spanish but 187 + 165= 352

Answer:

This would bring you to $160.00. This is because you initially had $20.00, because of the $13 and $7. Then, your family gave you a total of $140.00, and 140 + 20 = 160.

Step-by-step explanation:

The total amount of money he had is $160 and this can be determined by using the arithmetic operations and the given data.

Given :

The arithmetic operations can be used in order to determine the total amount of money he had.

The initial amount of money he had is:

= $13 + $7

= $20

His Mom gave him $10.00. So, the total amount of money now he had is:

= $20 + $10

= $30

His Dad gave him $30.00. So, the total amount of money now he had is:

= $30 + $30

= $60

His Aunt, Uncle, and Grandma gave him $100. So, the total amount of money now he had is:

= $60 + $100

= $160
