Answer:
the square root of 25 is 5
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
I believe its c if that is 31.5
The value of x is 5 since 5^2=25+2=27/3=9
Knowing the roots first write the equation in factored form:
(X - 3/4)(x +5) = 0
Now use the FOIL method ( multiply each term in one set of parentheses by each term the other set:
X•x + x•5 -3/4•x -3/4•5
Simplify:
X^2 + 5x -3/4x -3 3/4
Combine like terms:
X^2+ 4 1/4x - 3 3/4
