We have been given that there are s milligrams of vitamin C per milliliter of spinach, B mg per milliliter of berries, and D mg per milliliter of dressing.

Let us find how much mg of vitamin C our each ingredient of salad will have.

We have been given that a salad contains 300 milliliters of spinach, 200 ml of berries, and 42 ml of dressing.

$\text{Mg vitamin C in 300 ml spinach}=300\cdot\text{s mg}$

$\text{Mg vitamin C in 200 ml berries}=200\cdot\text{B mg}$

$\text{Mg vitamin C in 42 ml dressing}=42\cdot\text{D mg}$

To find total milligrams of vitamin C in our salad we will add milligrams of vitamin C in each of three ingredients of salad.

$T=(300s+200B+42D)\text{ mg}$

Therefore, our desired expression will be $T=(300s+200B+42D)\text{ mg}$ .

Answer:

Step-by-step explanation:

sin∅ = opposite side over hypotenuse

cos∅ = adjacent side over hypotenuse

To find <em>x</em>, there are multiple ways:

tan72° = 6/x

x = 6/tan72°

cos72° = x/15
