Answer:

B) \frac{DE }{EA} =\frac{CB}{AC}

Step-by-step explanation:

If ant two given triangles are SIMILAR, then they have equal corresponding angles and their corresponding sides are PROPORTIONAL.

For example: if Δ ABC ≈ Δ PQR, then

∠A  = ∠P  , ∠B  = ∠Q  and ∠C  = ∠R

and \frac{AB}{PQ} =  \frac{BC}{QR}  = \frac{AC}{PR}

Now, here given:  Δ ADE ≈ Δ ABC

Then by the SIMILAR postulate their corresponding angles are equal and their corresponding sides are Proportional.

\implies \frac{AD}{AB} =  \frac{DE}{BC}  = \frac{AE}{AC}    ............. (1)

Consider from above:

 \frac{DE}{BC}  = \frac{AE}{AC}\\\implies \frac{DE}{AE}  = \frac{BC}{AC} ............. (2)

Here, the given options are:

A) \frac{EA }{DE} =\frac{CB}{AC}     FALSE

B) \frac{DE }{EA} =\frac{CB}{AC}   TRUE    (from 2)

C) \frac{DE }{EA} =\frac{AC}{CB}   FALSE

C) \frac{EA}{DE} =\frac{AC}{CB}    FALSE

-5x+y=-3
serg [7]
(3)(-5x+y=-3)
(5)(3x-8y=24)

-15x+3y=-9
15x-40y=120

3y=-9
-40y=120

-37y=111
Divide both sides by -37

y=-3

To solve for x. Choose one equation from the given and plug what you get in Y.

I'll choose, -5x+y=-3
So, -5x+(-3)=-3
-5x=0
Divide both sides by -5
x=0/-5

Hope, this helps.
