Use a flowchart to prove if the triangles in each pair of similar. NO LINKS!!!<br>​

Answer:

Step-by-step explanation:

Start

<F = <Q                     Given

<GPF = <RPQ           Vertically opposite angles

<FGP = <QRP            A triangle has 180 degrees. 2 equal angles means the third pair must be equal

Triangle GPF ~ Triangle RPQ   AAA

end

I don't see any way to make these triangles similar except by stating the statement and why it is so. There really are no yes / no choices. If you get another answer, choose it.

JL/LE = 90/27                 Given

KL /LD = 90/27               Given

<JLK = <DLK                   Vertically opposite

Are the ratios equal       Yes  Then is the angle included Yes

Then the triangles are similar.

Are the ratios not equal  No then the triangles cannot be similar

Is the angle not included  Then similarity cannot be proved.

ΔJLK ≈ ΔDLK                  Equal Ratios and included angle === similarity

What is the answer to this?
Yanka [14]
DEF= 6 ft^2

A= 1/2*b*h

Plug in what you know.

6= 1/2*4*h

Multiply like terms. 

6=2*h

Divide 2 on both sides. 

3=h

If the base of ABC= 12

12/4=3

3*3=9

A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42

The area of ABC is 42 ft^2

I hope this helps!

[5x+10y+15z=60<br> [2x+4y+6z=60<br> [x+2y+3z=60
Alla [95]

Answer:

  no solution

Step-by-step explanation:

The equations are inconsistent. The set of equations reduces to ...

  x + 2y + 3z = 12

  x + 2y + 3z = 30

  x + 2y + 3z = 60

No values of x, y, and z can satisfy all three equations. There is no solution.

Helga [31]

Answer:

7 X / 2 y

Step-by-step explanation:

let Mel equals to X and female equals to y

therefore ×=y

therefore to make the count proper we have to multiply the male by 7

so 7 x = 2y and the fraction becomes 7 X / 2 y

hope this helps
