      Yes, good job Rahul .... The triangle with 3 : 4 : 5 is a right triangle. There for hypotenuse will be the diameter. The whole circle is divided into 3 arcs. The Longest one is a semicircle and the other two together make another semi circle. the ratio of central angles will be 1: 1

      @ Udhas ... 4th .. angle A = 33, therefore angle B = 90 -33 = 57. Angle d is also equal to 57 because they are angles in the same segment.

      6th .... AC = 4 CD = 2, DB = 3 { AC X CB = 20 and AD X DB = 18 }
      6 A is yet to complete. it is from tangents
