How did you find the angles? Also my computer says the answer to (a.) is incorrect.

PROBLEM NUMBER ONE: The closed-loop transfer function of a negative unity feedback system is given by (s + 4)(s − 1) - T(s) = 55 +254 +25³ +4² +5+2 Determine the systems stability using the Routh Hurwitz Criterion for Stability. Depending on the case, use the following required method: Case 1: Apply the usual procedure of the Routh array. Case 2: Apply the Reciprocal of Roots and Reverse Coefficients Case 3: Apply Auxiliary Polynomial
