Answer:
C. 5
> 15
Step-by-step explanation:
In the given series of inequalities, the inequality sign determines the final outcome.
A. 4
- 2 < 10
4
< 12
< 3
Since
< 3, then the inequality is false
B.
+ 9 < 12
< 3
Since
< 3, then the inequality is false
c. 5
> 15
> 3
Since
> 3, then the inequality is true
D. 6 > 2
3 > 
Since
< 3, then the inequality is false
Thus, the only inequality that is true is option C.
From trigonometry we know that:
if 
then,
(where
is an integer)
This can be rewritten in degrees as:
.............(Equation 1)
Now, in our case, 
Therefore, (Equation 1) can be written as:
..........(Equation 2)
Now, to find the correct options all that we have to do is replace n by relevant integers and find the values of
that match.
For n=2, (Equation 2) gives us:
.
Thus, 
Now, we know that: 
Let n=-1, then:

Thus, 
Likewise, 
Only the last option
will never match
because no integral value of
will ever give 
Thus the last option is the correct option.
