Answer: E) x = 19

<u>Step-by-step explanation:</u>

PA and TR are the top and bottom bases.

Therefore, ∠T ≅ ∠R and ∠P ≅ ∠A.

Thus, ∠P and ∠T are supplementary (sum equals 180°)

∠P + ∠T = 180

5x + 9 + 4x = 180

9x + 9 = 180

9x = 171

x = 19

Answer:

∠P + ∠T = 180

5x + 9 + 4x = 180

9x + 9 = 180

9x = 171

x = 19

Graph the image of the figure after a rotation of 90° counterclockwise.

I have no idea what figure you are talking about, but to make any figure rotate 90 counter - clockwise you would make the x value a negative like ( 1, 1) would become

0.2x-8=0.4x-7<br> What is x?

tensa zangetsu [6.8K]

Answer:

x = -5

Step-by-step explanation:

0.2x-8=0.4x-7

First, add 8 to both sides.

0.2x-8+8=0.4x-7+8

0.2x=0.4x-1

Next, subtract 0.4x from both sides.

0.2x-0.4x=0.4x-1-0.4x

-0.2x=1

Divide both sides by -0.2:

-0.2x/-0.2=1/-0.2

x=-5

Answer:

$36\sqrt{3} -12\pi$

Step-by-step explanation:

The area of the shaded portion, we have to calculate.

Now, join C and O to form two right triangles Δ AOC and Δ BOC.

Now, from Δ AOC,

$\tan 60 = \frac{AC}{AO} = \frac{x}{6}$

⇒ x = 6√3

So, area of Δ AOC = $\frac{1}{2} \times 6 \times 6\sqrt{3} = 18\sqrt{3}$

Due to symmetry area of Δ BOC will also be 18√3.

Now, area of quadrilateral OACB is 2 × 18√3 = 36√3

Now, area covered by the arc AB about center O will be $\frac{120}{360} \times \pi r^{2} = 12\pi$

Therefore, the area of the shaded portion is $36\sqrt{3} -12\pi$ (Answer)
