The value of x is 3.

In order to get this answer, you need to isolate the x. You do this by simply dividing both sides by 5. Dividing 5x by 5 will result In x and dividing 15 by 5 will result in 3. Therefore, x = 3

Answer:

8.9

Step-by-step explanation:

1. DE:BC=AD:AB

2. AD=AB+BD, but according to the conditions AB=5, then

AD=5+BD.

3. after the substitution DE=16; BC=9; AB=5 and AD=5+BD into the formula:

16:9=(5+BD):5;

\frac{16}{9} =\frac{BD+5}{5};

BD=80/9 - 5≈3.9.

4. if AD=AB+BD, then AD=5+3,9=8,9

Answer:

So the correct option is First one

i.e \dfrac{9\pi}{A}=\dfrac{90}{360}

Step-by-step explanation:

Given:

Area of Shaded part = 9 π square feet

To Find :

Area of Circle = ?

Solution:

90 degree center angle is equivalent to an area of 9 Π  square feet

So, 360 degree center is equivalent to area A which is the area of the complete circle.

So the Ratio will be

\dfrac{90}{9\pi} =\dfrac{360}{A}

Setting the given statements in proportion:

\dfrac{90}{9\pi} =\dfrac{360}{A}

On solving we get the required

\dfrac{9\pi}{A} =\dfrac{90}{360}

So the correct option is First one

i.e \dfrac{9\pi}{A}=\dfrac{90}{360}

Alternate Method:

Shaded part is of 90°

Area of Shaded part = 9 π square feet

And Full Circle is of 360° that is 4 sector of 90°

\textrm{Area of Circle}=4\times (Shaded\ part)

\textrm{Area of Circle}=4\times 9\pi

\textrm{Area of Circle}=36\pi

So the correct option is First one

i.e \dfrac{9\pi}{A}=\dfrac{90}{360}

On solving this we get

A=36\pi\ feet^{2}
