Answer:
the length of chord is 12cm.
Step-by-step explanation:
you can make the figure. the chord of the larger circle will become the tangent to the smaller circle.
make the radii
2 triangles will be formed. in one triangle apply the pythagoras theorem.
you will obtain the length of the half chord and then multiply it by 2.
this is how you would be able to get the length of the chord which is tangent to the other.
its just that simple.
I hope you understand.
