Use the Law of Sines to find the length of AC
ddd [48]
<h3>Answer:  30.78181 meters</h3>

The value is approximate. Round that however you need to.

========================================================

Explanation:

  • lowercase a = side opposite angle uppercase A
  • lowercase b = side opposite angle uppercase B
  • b = AC

Using the law of sines, we can say:

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

45/sin(30) = b/sin(20)

b/sin(20) = 45/sin(30)

b = sin(20)*45/sin(30)

b = 30.78181 approximately

You'll need to make sure your calculator is in degree mode.

Your parents have a realized income of $1,046.78/every 2 weeks. How much should the monthly housing expense budget be to stay wi
IgorLugansk [536]

Answer with explanation:

Income earned by my parents in every two weeks = $ 1046.78

In two weeks there are 14 days, so income earned by my parents in 1 day

              =\frac{1046.78}{14}\\\\74.77

Income of my parents after a month, if there are 30 days in a month = $74.77 × 30= $ 2243.10

We, will use ,\frac{28}{36} rule here , which states that , 28% of monthly income of my parents, should be used for  monthly housing expenses ,and 36% of gross monthly income should be used for debt purposes.

28% of $2243.78

=\frac{28}{100}*2243.78\\\\=\frac{62825.84}{100}\\\\=628.2584

= $ 628.26 (Approx)

So,my parents, monthly housing expense should not exceed ≥ $ 628.26
