Assuming that c is the length of AB (as is usually the case in the angle-side notation for triangles):
If sin(35) = 12/c, we can transform by multiplying both sides by c, and dividing both by sin(35) to get
c = 12/sin(35)
Evaluating using a calculator gives 20.92 units.

<u>Answer:</u>
$50 and $115
<u>Step-by-step explanation:</u>
We know that,
the sum of the two rates = $165 per hour
Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.
Then combining their charges together to get:

Solving for x to get:



So the rate charged per hour by one mechanic is $50 and for the other mechanic =
$115.
2000x(100%-29%)=1420
1420 of them did not have pets
Answer:
The set of vectors A and C are linearly independent.
Step-by-step explanation:
A set of vector is linearly independent if and only if the linear combination of these vector can only be equalised to zero only if all coefficients are zeroes. Let is evaluate each set algraically:
,
and
:



The following system of linear equations is obtained:



Whose solution is
, which means that the set of vectors is linearly independent.
,
and 



The following system of linear equations is obtained:


Since the number of variables is greater than the number of equations, let suppose that
, where
. Then, the following relationships are consequently found:




It is evident that
and
are multiples of
, which means that the set of vector are linearly dependent.
,
and 



The following system of linear equations is obtained:



Whose solution is
, which means that the set of vectors is linearly independent.
The set of vectors A and C are linearly independent.
