The reason why these triangles are similar is;

A. AA

Step-by-step explanation:

A two column proof can be presented using the drawing of the question diagram created with Microsoft Visio as follows;

Statement      [tex]{}[/tex]                  Reason

[tex]\overline {AB}[/tex] ║ [tex]\overline {DE}[/tex]   [tex]{}[/tex]                      Given

∠ACB ≅ ∠DCE       [tex]{}[/tex]         Vertically opposite angles

∠BAC ≅ ∠DEC       [tex]{}[/tex]         Alternate interior angles theorem

∠ABC ≅ ∠CED       [tex]{}[/tex]         Alternate interior angles theorem

ΔABC ~ ΔCDE        [tex]{}[/tex]         By Angle-Angle (AA) similarity postulate

Therefore, the correct option is AA.

Step-by-step explanation:

Answer:

The angle is 50 degrees.

Answer:

The Pythagorean Theorem is a squared + b squared = c squared. It is used to find out a side of a triangle if you already know the two others. C is always the H=hypotenuse, while the other two sides are a and b.

Answer: a^2+b^2 (factored) = c^2

Step-by-step explanation:

This only helps if you are solving for the hypotenuse.

Answer:

$30,750

Step-by-step explanation:.

Paso uno:

datos dados

costo del auto = $ 37,500

% degradación = 18%

= 18/100 * 37,500

= 0,18 * 37,500

= $ 6750

Segundo paso:

deje que el costo total sea T

Por lo tanto

T = coste del coche-% de degradación

T = 37.500-6750

T = 30,750

Answer:

f (4) = 21

Step-by-step explanation:

the given equation is f (x) = 4x + 5

putting the value of x = 4

we get, f (4) = (4×4) + 5

f (4) = 16 + 5

f (4) = 21

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

h=10 so plug that into the given equation

c=3(10) +50

c=30+50

c=80

Answer: C, c = $80

Step-by-step explanation:

c = 3h + 50

c = 3 (10) + 50

c = 30 + 50

c = 80

The total cost is $80

Hope that helped!

Answer:

the total earnings is $58

Step-by-step explanation:

The computation of earnings is shown below:

= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments

= (1 5 ÷ 12 × $10.50)  + (1 3 ÷ 4 × $10.50)  + (2 1 ÷ 3 × $10.50)

= 14.875 + 18.375 + 24.50

= $57.75

Hence, the total earnings is $58

The same is to be considered

Given:

The function is

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

To find:

The missing values for a, b, and c in the given table.

Solution:

We have,

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

At x=-2,

[tex]f(-2)=\left(\dfrac{1}{3}\right)^{-2}[/tex]

[tex]a=\left(3\right)^{2}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]a=9[/tex]

At x=-1,

[tex]f(-1)=\left(\dfrac{1}{3}\right)^{-1}[/tex]

[tex]b=\left(3\right)^{1}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]b=3[/tex]

At x=0,

[tex]f(0)=\left(\dfrac{1}{3}\right)^{0}[/tex]

[tex]c=1[/tex]         [tex]\left[\because a^0=1, a\neq 0\right][/tex]

Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.
