Find the length of common chord if radia of two intersecting circles are 120 and 160 . Distance between two center are 200.?

• formula of common chord is 2r1*r2/d
  
  2*120*160/200=192

• r1=120
  r2=160
  d=200
  dis=2*r1*r2/d
  dis=192

• write the Area of Triangle formed by the two radii and tha line joining their center by 2 equation , 1# by 1/2 r1 * r2 sin(theta) (angle between r1 and r2)
  2# by 1/2 base *altitude . Twice the altitude is the ans.
