Answer:

∠ A ≅ ∠ D

Step-by-step explanation:

We have to prove Δ ABC and Δ DEF are congruent or Δ ABC ≅ Δ DEF applying the Angle-Side-Angle or ASA rule.

In order to maintain the sequence, in ASA rule we have to make congruent two angles and one side in between them.

Therefore, if ∠ B and ∠ E are proved to be congruent and segment AB and segment DE are proved to be congruent, then we have to consider another two angles which must be ∠ A and ∠ D to be congruent.

Therefore, option D is correct. (Answer)

Answer:

12y +16yi

Step-by-step explanation:

The thing about complex numbers is that you can treat them as binomials and use all of the things you know about multiplying and factoring polynomials.

Here, we assume you have ...

(5 +2yi)(4 -3i) -(5 -2yi)(4 -3i)

The factor (4 -3i) can be factored out, so you have ...

= ((5 +2yi) -(5 -2yi))(4 -3i)

= (4yi)(4 -3i)

= 16yi -12yi²

At this point, the definition of i comes into play, and you replace i² with -1.

= 12y +16yi

On Monday, during a one day sale, the price of a suit was decreased by 20%. On Tuesday, the price of the suit was changed back t

nignag [31]

Answer:

25%

Step-by-step explanation:

If we consider the original price of the piece of suit is x.

Given that, on Monday during a one day sale, the price of the suit was decreased by 20%.

Therefore, the new price of the suit on Monday is $x( 1 - \frac{20}{100}) = 0.8x$ .

Now, the price of the suit on Tuesday was changed back to the original price i.e. x.

Therefore, the price is increase by (x - 0.8x) = 0.2x from the price of 0.8x.

So, the percentage change in price of the suit on Tuesday is $\frac{0.2x}{0.8x} \times 100 = 25$ %. (Answer)

Please help me with this , it would mean alot

algol [13]

Answer:

Step-by-step explanation:

21-26. a = v - u / t

=> a = 47 - 19 / 5

=> a = 28 / 5

=> a = 5.6 m/s²

27-32. avg. speed = distance / time

=> 40 m / 10 s

=> 4 m/s

33-38. velocity = distance / time

=> v = 150 / 40

=> v = 15 / 4

=> v = 3.75 m/s
