Answer:
see below
Step-by-step explanation:
Find the magnitude (-1)^2 + (sqrt3)^2 = m^2 m = 2
find the angle arctan (sqrt3/-1) = 120 degrees
the cube root would then be
(cos 40 + isin 40)
In the coordinates of A are (-2,3) and the coordinates of B are (7,-1), find the length of AB

Answer:
D = (-4, -4)
Step-by-step explanation:
Given;
midpoint of line CD = M(-3, -7)
coordinate of C = (-2, -10)
The coordinate of D is calculated as follows;
C(-2, -10)---------------------M(-3, -7)--------------------D
Therefore, the coordinate of D = (-4, -4)
