Answer:
Explanation:
vertices C and D have the same coordinate x and x of D = 7
hence
x of C = 7
vertices A and D have the same coordinate y and y of D = 2
hence
m = 2
and
m+3 = 2+3 = 5
and since vertices B and C have the same coordinate y and y of B = 5
hence
y of C = 5
thus
coordinates x, y of C: (7, 5)
