Answer:

  21.8 cm

Step-by-step explanation:

A useful way to write the Law of Sines relation when solving for side lengths is ...

  a/sin(A) = b/sin(B)

Then the solution for 'a' is found by multiplying by sin(A):

  a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)

__

We need to know the angle A. Its value is ...

  A = 180° -75° -31.8° = 73.2°

Then the desired length is ...

  a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)

  a ≈ 21.8 cm

_____

I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.

Most experts believe that young children’s not being
kipiarov [429]

(E) "the withholding of physical affection from young children interferes"

The mistake here is in the punctuation. The subject ("young...affection") and its verb are needlessly separated by a comma ("interferes"). Furthermore, the sentence's structure is complicated. Only E fixes these mistakes without introducing any new ones.

There is improper punctuation in Option (A). The subject ("young...affection") and its verb are needlessly separated by a comma ("interferes"). Uncertain pronoun references are present in Option (B). It's unclear to what the pronoun "it" refers.  

The incorrect usage of a definite article is in Option (C). The words "the failure" implies that the failure has already been discussed, yet this is false. Choice (D) uses inappropriate wording. "Withholding" is a verb without a subject.

Here's another question with an answer similar to this about punctuations: brainly.com/question/12933782

Help please!!!! Weekly time card $14.50 hr
olganol [36]

Answer:

123.25

Step-by-step explanation:

Am = 4 hours

4x14.5= 58

Pm = 4 hrs 30 mins

4x14.5=58

Then multiply 30(14.5) which gives you 435. Then divide by 60. That gives you 7.25

You could also divide 14.5 by 2 since 30 minutes is half of an hour.

Then add

58+58+7.25

123.25
