by decreasing 15 degree of each angle of a triangle the ratios of their anges are 2:3:5. the radian measure fo greatest angle is

• its 11pie/24...
  x-15:y-15:z-15=2:3:5
  2a+3a+5a=135
  a=135/10
  implies
  x=42
  y=55.5
  z=82.5
  all values of x,y,z are in degree so from above it is clear dat z is the gretest angle so we have to change it in radian...
  82.5*pie/180
  gives
  11*pie/24
