Answer:

x = 8/3

Step-by-step explanation:

6x-4=3x+4

Subtract 3x from each side

6x-3x-4=3x-3x+4

3x-4 =4

Add 4 to each side

3x-4+4 = 4+4

3x =8

Divide each side by 3

3x/3 = 8/3

x = 8/3

Special right triangles, find x and y
egoroff_w [7]

Answer:

The answer to your question is x = 17.32; y = 8.67

Step-by-step explanation:

Process

1.- Use trigonometric functions to find x and y

   a) sin Ф = \frac{opposite side}{hypotenuse}

      Ф = 60°

      opposite side = 15

      hypotenuse = ?

     hypotenuse = \frac{opposite side}{sin \alpha }

     hypotenuse = \frac{15}{sin 60}

     hypotenuse = \frac{15}{0.87}

            hypotenuse = 17.32

     b) cosФ = \frac{y}{hypotenuse}

         y = hypotenuse x cos 60

         y = 17.32 x 0.5

                y = 8.67
