Question

I need help please the friends would greatly appreciate it. plotted in the complex plane ... :)

Answer 1

Attached is a picture showing the plot in the plane.
Note that for a complex number ,  x + iy.
The real part of the number is put on the x axis and the imaginary part is put on the y axis.

So plotting:
A = 4 + 1i
B = 9 + 7i
C = 5 + 8i
 
See picture.
