Answer:
C. 
Step-by-step explanation:
We need to determine whether the given polynomial
can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.









Hence final answe is choic C. 
Use the cosine law to answer the question which can be expressed as,
c² = a² + b² -2ab(cos C)
where c is the side opposite to angle C and a and b are the sides adjacent to the angle. Substituting the given values,
c² = 33² + 37² - (2)(33)(37)(cos 120°) = 3679
The value of c is 60.65. Therefore, the length of the third side is approximately 60.65 units.
