Can you please help me answer number 14?

14. (L93) Identify the polar (trigonometric) form of the complex number z = -6 + (-9i). Any quantities that are not whole numbers should be rounded to one decimal place. A. z = 10.8 (cos 33.7 + isin 33.70) B. z = 10.8 (sin 56.3 + icos 56.30) C. z = 10.8 (cos 123.7 + isin 123.70) D. z= 15 (cos 56.3 + isin 56.39) E. z = 10.8 (cos 236.3 + isin 236.39)
