Answer:

168

Step-by-step explanation:

- first we need to find the third angle of the triangle, and since 180 is the sum of all angles, 180 - 90 - 78 = 12

- 12 is the interior angle at point 1, the exterior angle is 180 - 12 = 168

(here we use 180 because its a straight line)

The measure of  21 (exterior to the triangle) is 168 degrees.

The calculation is as follows:

= 180 - 90 -78

= 12

= 180 - 12

= 168

Therefore we can conclude that the measure of  21 (exterior to the triangle) is 168 degrees.

Step-by-step explanation:

Answer:

d

Step-by-step explanation:

the answer is 12% decrease in area

The required, percentage decrease in the area of the triangle is 12%. Option D is correct.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Area of the triangle = 1/2bh

Now,
The length of the base of a triangle is increased by 10 percent and the height is decreased by 20 percent,
base = b + 0.1b = 1.1b
height = h - 0.2h = 0.8h

New area = 1/2[1.1b][0.8h] = 0.88 [1/2b/h]

Percentage decrease in area = [ 1/2bh - 0.88 [1/2b/h] / 1/2bh × 100%
                                             = 12%

Thus, the required, percentage decrease in the area of the triangle is 12%. Option D is correct.

Answer:

The answer is B. But honestly tempeture rises with every layer.

$231,000.

We have been given that a 2,100 square foot home in Cheyenne Wyoming costs $110 per square feet.

To find the total cost of home we will multiply the total area of home by the cost of per square feet area.

2,100 × 110 = 231,000$

Answer:

length = 20 feet

width = 7 feet

Step-by-step explanation:

This problem can be solved using a system of equations. Using the given information, you can formulate 2 equations:

l*w = 140

l = 2w + 6

In order to solve this system of equations, you can use the Substitution Property of equality to substitute the l in the first equation for (2w + 6) in order to find the width:

where l*w = 140 and l = 2w + 6,

1. (2w + 6)*w = 140

2. 2w^2 + 6w = 140

3. w^2 + 3w = 70

4. w^2 + 3w - 70 = 0

5. (w - 7) (w + 10) = 0

6. w = 7, -10

1. Substitution

2. Simplification

3. Divide both sides by 2

4. Subtract 70 from both sides

5. Factor the left side (find 2 numbers that add to 3 and multiply to -70)

6. Solve for w

The width must be 7 because a width of -10 is impossible. Now, you just need to plug that into the equation to solve for l:

l*w = 140

7l = 140

l = 20

That means that the length is 20 and the width is 7.

Answer:

Size of V = 95°

Step-by-step explanation:

The total sum of angles in a triangle is 180°

You can find Angles T and V.

2x+3x+5 = 180°-25°

5x+5 = 155°

5x = 155°-5

    = 150°

x = 150°÷5

  = 30°

Angle V = 3×30°+5

             = 95°

each marker is placed at 5 gallons up, and one minute over. (up 5, over one AKA 5 over one) 5/1. Hope this helped :)

Answer:

the third one is correct

explanation:

the second dot on the graph shows that it is ten gallons of water for 2 minutes, making the fraction 10/2. That simplifies to 5/1, which is the third answer.

Answer:

The volume of the tetrahedron is

[tex]\frac{-32}{3}[/tex]

Step-by-step explanation:

To find the volume of a tetrahedron with vertices (2, 0, 0), (0, 4, 0), (0, 0, 4), (2, 4, 4).

We know by definition that the volume of a tetrahedron with vertices [tex](x_{1}, y_{1}, z_{1}), (x_{2}, y_{2}, z_{2}), (x_{3}, y_{3}, z_{3})[/tex] is

[tex]\frac{1}{6}\begin{vmatrix}

2 & 0 & 0 & 1\\

0 & 4 & 0 & 1\\

0 & 0 & 4 & 1\\

2 & 4 & 4 & 1

\end{vmatrix}[/tex]

From here we have:

[tex]\frac{1}{6}\begin{vmatrix}

x_1 & y_1 & z_1 & 1\\

x_2 & y_2 & y_2 & 1\\

x_3 & y_3 & z_3 & 1\\

x_4 & y_4 & y_4 & 1

\end{vmatrix}[/tex]

Finding the determinant of that matrix we have:

[tex]\frac{1}{6} (-64)[/tex] = [tex]\frac{-32}{3}[/tex]

Answer:

-5
