Answer:

Step-by-step explanation:

You can figure out the angle DBC by the alternate interior theorem. Angle DBC=56 degrees. You already figured out BD.

Since we know BD, BC, and the angle DBC we can use the Law of cosine to find CD

The law of cosine is

CD^2=BC^2+BD^2-2(BC)(BD)cos DBC

Plug in what we know

CD^2=18^2+12.1^2-2(18)(12.1)cos 56

CD^2≈228.8387

Find the square root to isolate CD.

CD≈15.1

Answer:

The area of the floor space is equal to 5.83 sq yards.

Step-by-step explanation:

Given that,

Each row requires a section of floor that is 1 ¾ yards by 3 ⅓ yards.

We need to find how many square yards of floor space are taken up by one row of cheerleaders.

We know that, the area of a rectangle is given by :

A = lb

So,

$A=\dfrac{7}{4}\times \dfrac{10}{3}\\\\A=5.83\ yards^2$

So, the area of the floor space is equal to 5.83 sq yards.

What is an equation of a circle with center (2,7) and radius 4?

goblinko [34]

Equation of a circle:

(x - h)^2 + (y - k)^2 = r^2

In this case:

<span>center (2,7) and radius 4 so h = 2, k = 7 and r = 4

</span>Equation:

(x - 2)^2 + (y - 7)^2 = 4^2

(x - 2)^2 + (y - 7)^2 = 16

Hope it helps.
