Find the missing side lengths. leave your answers as radicals in simplest form.
Murrr4er [49]

Answer:

x = 4 , y = 2

Step-by-step explanation:

Using the sine / tangent ratios in the right triangle and the exact values

sin60° = \frac{\sqrt{3} }{2} and tan60° = \sqrt{3} , then

sin60° = \frac{opposite}{hypotenuse} = \frac{2\sqrt{3} }{x} = \frac{\sqrt{3} }{2} ( cross- multiply )

x \sqrt{3} = 4\sqrt{3} ( divide both sides by \sqrt{3} )

x = 4

and

tan60° = \frac{opposite}{adjacent} = \frac{2\sqrt{3} }{y} = \sqrt{3} ( multiply both sides by y )

y \sqrt{3} = 2\sqrt{3} ( divide both sides by \sqrt{3} )

y = 2

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is  y  =  5sin3x

Step-by-step explanation:

From the question we are told that  

   y =  c_1\ cos3x + c_2 \  sin 3x

given that y(0) =  0

We have that  

     c_1\ cos3(0) + c_2 \  sin 3(0)  =  0

=>   c_1 =  0

This means that

           y  =  c_2 \  sin 3x

We also given that

          y[\frac{\pi}{6} ] =  5

So  

         c_2  sin (3 *  \frac{\pi}{6} )  =  5

=>    c_2  =  5

Hence  

     y  =  5sin3x

Working together, 5 friends collected 15 5/8 bags of food for the homeless. On average, how many bags of food did each friend co
Effectus [21]

15 5/8 divided by 5

First, we turn the 15 5/8 to a mixed number: 8 * 15 + 5 = 125/8

125/8 divided by 5/1 (which is equal to 5)

Next, we do Keep Change Flip.

Keep 125/8 the same, change the division to multiplication, and turn the 5/1 to 1/5.

1 * 125 = 125

8 * 5 = 40

Then, we get 125/40 = 3 5/40 BUT WAIT

We can reduce it once more! Divide 40 by 5

Each friend collected 3 1/8 bags of food.
