Let C be a circle with centre P

_{0}and AB be a diameter of C. Suppose P_{1}is the mid point of the line segment P_{0}B, P_{2}is the mid point of the line segment P_{1}B and so on. Let C_{1}, C_{2}, C_{3}, ...... be circles with diameters P_{0}P_{1}, P_{1}P_{2}, P_{2}P_{3}... respectively. Suppose the circles C_{1,}C_{2}, C_{3}, .... are all shaded. The ratio of the area of the unshaded portion of C to that of the original circle C is?The lines represented by the three equations

2X+3Y-5=0: 3X-5Y+2=0, and -5X+2Y+3=0

In the adjoining figure, chord ED is parallel to the diameter AC of the circle. If Angle CBE = 65 degree, then what is the value of DEC?
