If one angle of a cyclic trapezium is triple the other,
then the greater one measures :
(a) 90º (b) 105º (c) 120º (d) 135º

• (d) 135 degrees
  Opposite angles of a cyclic quadrilateral are supplimentary i.e. their sum is 180 degrees.
  If one angle is thrice the other then x + 3x = 180
  So x = 45 degrees
  So greater angle i.e. 3x = 135 degrees.
