Answer:
z = -8.46 - 3.08i.
Step-by-step explanation:
cos 200 = -0.93969 so 9 * cos 200 = -8.46 to the nearest hundredth.
sin 200 = -0.3420 so 9 * sin 200 = -3.08 to nearest hundredth.

Adjacent interior angle = x
Sum of exterior angle and adjacent interior angle = 180
35 + x = 180
x = 180 - 35
x = 145
3×-4=a
a=-12
b×(-3)= -12
-3b= -12
b=-12
-12c=12
c=-1
d×24= -12
24d= -12
d= -1/2 or -0.5
