Explain why ΔABC cannot be shown to be congruent to ΔCDA.

Mathematics
1 answer:
igomit [66]3 years ago

There isn't enough info to prove the triangles to be congruent or not. So we can't say for sure either way.

We have angle CAD = angle ACB given by the arc markings, and we know that AC = AC due to the reflexive theorem. However we are missing one third piece of information.

That third piece of info could be....

  • AD = BC which allows us to use SAS
  • angle ACD = angle CAB which allows us to use ASA
  • angle ABC = angle CDA which allows us to use AAS (slight variation of ASA)

Since we don't know any of those three facts, we simply don't have enough information.

side note: If AB = CD, then this leads to SSA which is not a valid congruence theorem. If we had two congruent sides, the angle must be between the two sides, which is what AD = BC allows.

Answer:

Arithmetic: (4, 8, 12, 16, ...) (3, 8, 13, 18, ...)

Geometric: (2, 6, 18, 54, ...) (5, 10, 20, 40, ...)

Neither arithmetic or geometric: (5, 10, 20, 30, ...)

Step-by-step explanation:

Arithmetic sequences are sequences where all of the numbers have a common difference.

4, 8, 12, 16, ... all have a common difference of 4.

3, 8, 13, 18, ... all have a common difference of 5.

Geometric sequences are sequences where all of the numbers have a common ratio.

2, 6, 18, 54, ... all have a common ratio of 3.

5, 10, 20, 40, ... all have a common ratio of 2.

Sequences that are neither arithmetic or geometric do not have common differences or common ratios.

5, 10, 20, 30, ... does not have a common difference or a common ratio

24-4x=2x<br> show your work, will mark brainliest
vladimir2022 [97]

Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

24−4x=2x

24+−4x=2x

−4x+24=2x

Step 2: Subtract 2x from both sides.

−4x+24−2x=2x−2x

−6x+24=0

Step 3: Subtract 24 from both sides.

−6x+24−24=0−24

−6x=−24

Step 4: Divide both sides by -6.

−6x /−6  = −24 /−6

x=4
