Answer: The percent error in the player's guess is 9.5%.
Step-by-step explanation:
Given : A basketball player guesses her team will score 57 points during the game.
The player's team actually scores 63 points.
i.e. The actual core = 63 points
The estimated score = 57 points
Then , the percent error in the player's guess would be :
Hence, the percent error in the player's guess is 9.5%.

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.
For this case we have to:
Given the quadratic equation of the form:
The roots are given by:
If we have:
We can rewrite it in the following way:
Where:
Where we have:
By definition:
Thus, the roots are given by imaginary numbers:
