Answer 1

Answer:

I think it is 12 cm.

Step-by-step explanation:

I extended BC to a point D and drew a perpendicular from A as mentioned.

So, I got a right triangle ADC with hypotenuse 15 cm.

In my mind, suddenly striked that DC should be 9 cm according to the diagram by some calculations.

So the length of AD should be 12 cm.

I'm not sure about this. If there is any ambiguity, I'm sorry for that.
