Quadilateral ABCD is similar to quadilateral EFGD Help?

<span>The figure shown below is an example of ratio and proportion. A ratio is a comparison between two different things. A proportion is two ratios that have been set equal to each other. Note that in the figure shown below, the form and angle of quadilateral ABCD is similar to quadilateral EFGD. So if we have angle ABC, it is proportional to angle EFG or angle E. From the question, angle CGF is proportional to angle GDE or angle D.</span>

This is a sadly defective question.

It wants you to mark "Angle D", because Angle-D is
equal
to angle-CGF ... they're the same size.
 
But they are not "corresponding" angles.

Angle-CGF is an angle outside of the smaller figure.
The corresponding angle of the larger figure would be
the angle above and outside of corner-C, if the side DC
were extended a little bit to make an angle up there.

A family has an annual income of ​$30,600 Of​ this, 1/4 is spent for​ food, 1/5 for​ housing, 1/10 for​ clothing, 1/9 for​ savin
Ksenya-84 [330]

Answer:

$6,120

Step-by-step explanation:

1/5 (one-fifth) of the family's annual income ($30,600) is spent on housing- as the word problem states.

You have to find 1/5 (one-fifth) of* $30,600.

Write it out as an equation.

\frac{1}{5}  \times 30600

*The <em>of</em><em> </em>in the word equation (1/5 of 30600) simply means multiplication.

Is the given point interior , exterior, or on the circle k (x+2)2 + (y-3)2 =18 P (8,4)
Mnenie [13.5K]
One way would be to find the distance from the point to the center of the circle and compare it to the radius

for
(x-h)^2+(y-k)^2=r^2
the center is (h,k) and the radius is r

and the distance formula is
distance between (x_1,y_1) and (x_2,y_2) is
D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}


r=radius
D=distance form (8,4) to center

if r>D, then (8,4) is inside the circle
if r=D, then (8,4) is on the circle
if r<D, then (8,4) is outside the circle


so
(x+2)^2+(y-3)^2=18
(x-(-2))^2+(y-3)^2=(\sqrt{18})^2
(x-(-2))^2+(y-3)^2=(3\sqrt{2})^2

the radius is 3\sqrt{2}
center is (-2,3)

find distance between (8,4) and (-2,3)

D=\sqrt{(8-(-2))^2+(4-3)^2}
D=\sqrt{(8+2)^2+(1)^2}
D=\sqrt{10^2+1}
D=\sqrt{100+1}
D=\sqrt{101}




r=3\sqrt{2}≈4.2
D=\sqrt{101}≈10.04

do r<D

(8,4) is outside the circle

In order to solve the following system of equations by subtraction, which of the following could you do before subtracting the e
Whitepunk [10]
I can't see the options, but you would need to multiply (4x - 2y = 7) by 3, and (3x - 3y = 15) by 4 so that you get 12x in both equations. Then when you subtract, you eliminate 12x. I hope this helps!
