[tex] \cot(A) = \frac{AC}{BC} \\ [/tex]

[tex] \cot(60°) = \frac{AC}{8 \sqrt{3} } \\ [/tex]

[tex] \frac{1}{ \sqrt{3} } = \frac{AC}{8 \sqrt{3} } \\ [/tex]

[tex] \frac{AC}{8 \sqrt{ 3} } = \frac{1}{ \sqrt{3} } \\ [/tex]

Multiply sides by 8√3

[tex]8 \sqrt{3} \times \frac{AC}{8 \sqrt{3} } = 8 \sqrt{3} \times \frac{ 1 }{ \sqrt{3} } \\ [/tex]

[tex]AC = 8[/tex]

Answer:

Please find attached a drawing of the triangles ΔRST and EFG showing the angles

The angle on ΔEFG that would prove the triangles are similar is ∠F = 25°

Step-by-step explanation:

In order to prove that two triangles are similar, two known angles of each the triangles need to be shown to be equal

Given that triangle ∠R and ∠S of triangle ΔRST are 95° and 25°, respectively, and that ∠E of ΔEFG is given as 90°, then the corresponding angle on ΔEFG to angle ∠S = 25° which is ∠F should also be 25°

Therefore, the angle on ΔEFG that would prove the triangles are similar is ∠F = 25°.

We can solve this problem by testing the solution against each system of equations. We'll do this by substituting the point into each equation for each system.

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}2x+y&=5\\2(2)+1&=5\\4+1&=5\\5&=5\\&\checkmark\end{aligned}&\begin{aligned}-2x+y&=2\\-2(2)+1&=2\\-4+1&=2\\-3&=2\\&\text{X}\end{aligned}\end{array}[/tex]

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}-2x-y&=-5\\-2(2)-1&=-5\\-4-1&=-5\\-5&=-5\\&\checkmark\end{aligned}&\begin{aligned}2x-y&=2\\2(2)-1&=2\\4-1&=2\\3&=2\\&\text{X}\end{aligned}\end{array}[/tex]

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}-x+y&=3\\-2+1&=3\\-1&=3\\&\text{X}\end{aligned}&\begin{aligned}-3x+y&=-5\\-3(2)+1&=-5\\-6+1&=-5\\-5&=-5\\&\checkmark\end{aligned}\end{array}[/tex]

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}x+y&=3\\2+1&=3\\3&=3\\&\checkmark\end{aligned}&\begin{aligned}3x-y&=5\\3(2)-1&=5\\6-1&=5\\5&=5\\&\checkmark\end{aligned}\end{array}[/tex]

Since both equations in the final system are true when solved with [tex](2, 1)[/tex], the answer is the last system.

We use a similar strategy as in your previous question. Rewrite:

sin(5x) = sin(6x - x) = sin(6x) cos(x) - cos(6x) sin(x)

sin(7x) = sin(6x + x) = sin(6x) cos(x) + cos(6x) sin(x)

→ sin(5x) - sin(7x) = -2 cos(6x) sin(x)

sin(4x) = sin(6x - 2x) = sin(6x) cos(2x) - cos(6x) sin(2x)

sin(8x) = sin(6x + 2x) = sin(6x) cos(2x) + cos(6x) sin(2x)

→   sin(8x) - sin(4x) = 2 cos(6x) sin(2x)

cos(5x) = cos(6x - x) = cos(6x) cos(x) + sin(6x) sin(x)

cos(7x) = cos(6x + x) = cos(6x) cos(x) - sin(6x) sin(x)

→   cos(7x) - cos(5x) = -2 sin(6x) sin(x)

cos(4x) = cos(6x - 2x) = cos(6x) cos(2x) + sin(6x) sin(2x)

cos(8x) = cos(6x + 2x) = cos(6x) cos(2x) - sin(6x) sin(2x)

→   cos(4x) - cos(8x) = 2 sin(6x) sin(2x)

Then

(sin(5x) - sin(7x) - sin(4x) + sin(8x)) / (cos(4x) - cos(5x) - cos(8x) + cos(7x))

= (2 cos(6x) sin(2x) - 2 cos(6x) sin(x)) / (2 sin(6x) sin(2x) - 2 sin(6x) sin(x))

= (2 cos(6x) (sin(2x) - sin(x))) / (2 sin(6x) (sin(2x) - sin(x)))

= cos(6x) / sin(6x)

= cot(6x)

Step-by-step explanation:

Assume;

Given number is x

So,

Subtracted from 7;

x - 7

Divided by 2

(x-7)/2

Multiplied by 4

[(x-7)/2]4

Product was 4

Answer:

The angle for C is 28°.

Step-by-step explanation:

In a cyclic quadrilateral, opposite angles are supplementary which means that both angles add up will be 180° :

∠A + ∠C = 180°

152° + ∠C = 180°

∠C = 180° - 152°

∠C = 28°

B. 28

Answer:

division property of equality

Step-by-step explanation:

The property used in the last step to find x = 10 in the expression is the division property of equality.

      8(x-2) = 64

      8x-18 = 84

        8x = 80

         x = 10

In 8x = 80 ;

 Division property of equality was used to find the value of x.

The property states that when we divide both sides by a non-zero value, the two sides remains the same.

Answer:

[tex]\frac{63}{5}[/tex]

Step-by-step explanation:

 Given expression:

    (3) 4[tex]\frac{1}{5}[/tex]  

The distributive law is mostly applied to multiplication and division which helps to expand a parentheses;

   4[tex]\frac{1}{5}[/tex]   can be written as [tex]\frac{21}{5}[/tex]  

 Now;

         (3) [tex]\frac{21}{5}[/tex]  

 With distributive property, we simply multiply the two terms;

           3  x [tex]\frac{21}{5}[/tex]     = [tex]\frac{63}{5}[/tex]

Answer:

Rewrite 3 ( 4   1 /5  ) as 3 ( 4 +  1 5  ) . Distribute the 3 to get 3(4) + 3 (  1 /5  ) . Multiply to get 12 +   3 /5  . Then add to get 12  3 /5

Answer:

60%

Step-by-step explanation:

:))))))

step 1 Address the formula, input parameters & values

Formula :

Increase

Initial Value

x 100 = Percent Increase (%)

Initial Value X = 250 & New Value Y = 400

Increase = (Y - X)

(400 - 250)

250

x 100 = ?

step 2 Apply the values in the percentage increase {(Y - X)/X x 100} formula

=(400 - 250)

250

x 100

=150

250

x 100

= 60%

(400 - 250)

250 x 100 = 60%

60 percent increase (%↑) or raise from 250 is 400 or 160% of 250 is 400

Answer:

62.5%

Step-by-step explanation:

Divide 250 by 400 to get 0.625. Then, multiply by 100 to get the percentage, 62.5%.
