Nope, the answer is three. Mean means the average of all the numbers. So all you have to do is to add the numbers up and divide the the amount of numbers with your sum.
Answer:
m = x
Step-by-step explanation:
y = mx + b
Mx will always be slope if the equation.
Answer:

and

respectively.
Step-by-step explanation:
The given trigonometric equation is

We divide both sides by
to get,

This implies that,

We take the inverse tangent of both sides to get,




Since the tangent ratio has a period of
, another solution is

to the nearest degree.
In the third quadrant,




The solutions are

The value of x that satisfies the equation if x lies in the second quadrant is 
The value of x that satisfies the equation if x lies in the third quadrant is
