Answer:

Option C. Transitive property of equality

Step-by-step explanation:

It is given in the question AB ≅ CD and CF ≅ EB

and we have to prove that AE ≅ FD

Since AB = AE + EB

and CD = CF + FD

AB ≅ CD [Given]

So, AE + EB ≅ CF + FD

Since CF ≅ EB  [Given]

So, AE ≅ FD [Transitive property]

Hence Option C. Transitive property of equality will be the answer.

Find the x-values that are solutions of the equation 5cot^2x-15=0
julia-pushkina [17]
First solve for the trig function 'cot'
cot^2 x = \frac{15}{5} = 3

Next take the sqrt of both sides (include plus/minus)
cot x = \pm \sqrt{3}

Now take reciprocal of both sides, this will change trig function to 'tan'
(cot = 1/tan)

tan x = \pm \frac{1}{\sqrt{3}} = \pm \frac{\sqrt{3}}{3}

Finally use the unit circle or inverse tan on your calculator to find x.
There will be 4 solutions, one for each quadrant.

x = \frac{\pi}{6}, \frac{5\pi}{6}, \frac{7\pi}{6}, \frac{11\pi}{6}

What is the area of the shaded portion of the circle?
SOVA2 [1]

Answer:

The first option is the correct one, the area of the shaded portion of the circle is

[/tex](5 \pi -11.6)ft^2[/tex]

Step-by-step explanation:

Let us first consider the triangle + the shadow.

The full area of the circle is the radius squared times pi, so

A=(5 ft)^2 \cdot \pi \\25 ft^2 \cdot \pi

Since \frac{72^{\circ}}{360^{\circ}}=\frac{1}{5}, the area of the triangle + the shaded area is one fifth of the area of the whole circle, thus

A_1=\frac{1}{5}25 ft^2 \cdot \pi\\ =5 ft^2 \cdot \pi

If we want to know the area of the shaded part of the circle, we must subtract the area of the triangle from A_1.

The area of the triangle is given by

A_{triangle}=\frac{1}{2}\cdot (2.9+2.9)ft \cdot 4 ft\\= 11.6 ft^2

Thus the area of the shaded portion of the circle is

A_1-A_{triangle}=5 \pi ft^2-11.6ft^2\\= (5 \pi -11.6)ft^2
