Therefore \theta = 30^\circ

Step-by-step explanation:

Given,

4\sqrt{3 } =8 cos \theta

\Leftrightarrow cos \theta =\frac{4\sqrt{3} }{8}

\Leftrightarrow cos \theta =\frac{\sqrt{3} }{2}

\Leftrightarrow cos \theta =cos 30^\circ

\Leftrightarrow  \theta = 30^\circ

Therefore \theta = 30^\circ

Identify which line from the graph the following right triangles could lie on.
qaws [65]

Answer:

Step-by-step explanation:

Slope of line A = \frac{\text{Rise}}{\text{Run}}

                         = \frac{9}{3}

                         = 3

Slope of line B = \frac{9}{6}

                         = \frac{3}{2}

Slope of line C = \frac{6}{8}

                         = \frac{3}{4}

5). Slope of the hypotenuse of the right triangle = \frac{\text{Rise}}{\text{Run}}

                                                                                = \frac{90}{120}

                                                                                = \frac{3}{4}

Since slopes of line C and the hypotenuse are same, right triangle may lie on line C.

6). Slope of the hypotenuse = \frac{30}{10}

                                              = 3

Therefore, this triangle may lie on the line A.

7). Slope of hypotenuse = \frac{18}{24}

                                        = \frac{3}{4}

Given triangle may lie on the line C.

8). Slope of hypotenuse = \frac{21}{14}

                                        = \frac{3}{2}

Given triangle may lie on the line B.

9). Slope of hypotenuse = \frac{36}{24}

                                        = \frac{3}{2}

Given triangle may lie on the line B.

10). Slope of hypotenuse = \frac{48}{16}

                                          = 3

Given triangle may lie on the line A.

Could someone please help with this question
Tcecarenko [31]
Change the fraction to a improper fraction.

11/9 + 10/9

Since they have the same denominators you can add them.

11/9 + 10/9 = 21/9

The answer is 21/9

Hope this helps :)

4 (2x-6)=10x-6. solve for x
Reika [66]

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

   4*(2*x-6)-(10*x-6)=0 


   2x - 6  =   2 • (x - 3) 

   8 • (x - 3) - (10x - 6) = 0 

   -2x - 18  =   -2 • (x + 9) 

 -2 • (x + 9) = 0 

Solve :    -2   =  0

<span>This equation has no solution.
</span>A a non-zero constant never equals zero.

Solving a Single Variable Equation : 
 Solve  :    x+9 = 0 

<span>
 </span>Subtract  9  from both sides of the equation :<span> 
 </span>                     x = -9
