Answer:

we can use trigonometric ratios (cos, sin, tan) to solve this

$cos(54)=AD/20\\20cos(54)=AD\\AD=12\\$

Using the pythagorean theorum we see that BD is 16

now we can use tan to solve for DC

$tan(28)=16/DC\\DC=16/tan(28)\\DC=30\\30+12=42; AC=42$

Answer:

68 ft^2

Step-by-step explanation:

The shaded region is a square missing a triangle. Thus, the area of the shaded region = area of square - area of triangle

Thus, we get 8*9 - 1/2 * 2 * 4 = 72 - 4 = 68 square feet.

Alison's dog eats 8 ounces of dog food each day. Alison bought a 28-pound bag of dog food. How many 8 ounce servings are in a 28

balandron [24]

To find this, we must first know how many ounces are in a pound. There are 16 ounces in a pound, which means that for every pound of dog food, Allison's dog gets 2 servings.

With this logic in mind, we can simply multiply 28 by 2 to represent 2 servings of food per pound. When we do this, it yields a result of 56.

Therefore, there are 56 servings in this bag of dog food.
