triangle.
7.9.2 In the diagram below, ADCB is a kite with A(3;5) and B(-1,-4). AD=DC and AB=BC.D
is the point such that AD is parallel to the x-axis and AD=5 units. CD is perpendicular to the x-axis. The diagonals intersect at P. A(3;5), B(-1;-4)

a) Show that the coordinates of C are (8;0).
b) Write down the coordinates of P.
c) Calculate the gradient of line AB.
d) Calculate the gradient of line AC.
e) Calculate the area of the kite ADCB.
