this is my second time posting the same question so pls make sure the ANSWER is correct (include the value of theta in the answer )

(a) Using a trig identity, write x(t) = -5 cos(4t) – 4 sin(4t) using only one cosine function. x(t) = || help (formulas) (b) Using a trig identity, write r(t) = 5 cos(4t) – 4 sin(4t) using only one cosine function. x(t) = help (formulas) (c) Using a trig identity, write r(t) = e-3 (-5 cos(4t) – 4 sin(4t)) using only one cosine function in your answer. x(t) = help (formulas)
