Question 13

In triangle $A B C$ , $A B = x$ , $A C = y$ and angle $60^\circ$ . It is given the area of $2\sqrt{3}(x+y)\text{ cm}^2$ .

Show that $8 x + 8 y = x y$

[3]

When the vertices of the triangle are placed on the circumference of a circle, $AC\,$ is a diameter of the circle. Determine the value of $x\,$ and the value of $y$ .
