Help anyone pleaseeee
AlexFokin [52]

Answer:

36 <127

(36,127°)

36 [ cos (127) + i sin (127)]

Step-by-step explanation:

w1 = 2 < 95

w2 = 18 < 32


w1 * w2

We multiply the magnitude and add the angles

w1 * w2 = 2*18 < (95+32)

            =36 < 127

             36 [ cos (127) + i sin (127)]
