Answer 1

Answer:

18 cm

Step-by-step explanation:

We know that the tangent to the smaller circle will be perpendicularly bisected by the radius of small circle. Also, radius of bigger circle will work as hypotenuse of the right triangle. Radius of the smaller circle will work as a perpendicular for the same. Now, by Pythagoras theorem, we will know that base of this right triangle will be 9 cm. But, we know that base of this right triangle is half the tangent (or the chord which is mentioned in the question). So, length of the tangent is 18 cm. Please mark as brainliest if you understand.
