Answer:

(A)AC=DF is correct

Step-by-step explanation:

It is given that AB=DE and ∠A=∠D and  we have to prove ΔABC≅ΔDEF, then

From ΔABC and ΔDEF, we have

AB=DE(given)

∠A=∠D(given)

AC=DF (because given triangles are congruent)

Thus, by SAS rule, ΔABC≅ΔDEF

Therefore, in order to prove that ΔABC≅ΔDEF by SAS rule, we need AC≅DF.

Thus, option A is correct.

Because you know that A and D are equal and AB and DE are equal, the answer would be A.

An animal shelter is building new cages for 26 dogs and 34 cats. All the animals are kept separate. The first crew can build a c
Oliga [24]

The animal shelter is building cages for 26 dogs and 34 cats.

26 + 34 = 60

It needs to build 60 cages.

The first crew builds 1 cage in 1 hour. Rate: 1 cage/hour

The second crew builds 1 cage in 2 hours, or 1/2 cage in 1 hour. Rate: 1/2 cage/hour

They work together for x hours and build all 60 cages.

In x hours, the first crew builds 1 cage/hour * x hours = x cages.

In x hours, the second crew builds 1/2 cage/hour * x hours = 1/2 x cages.

Combined, they build 60 cages.

x + 1/2 x = 60

x + 0.5x = 60

1.5x = 60

x = 40

Answer: It will take 40 hours.

Check: In 40 hours, the first crew builds 40 cages.

In 40 hours, the second crew builds 20 cages.

40 + 20 = 60

In 40 hours, the two crews build 60 cages.

Our answer above is correct.
