Answer 1

Answer:

question is not correct

Answer 2

Answer:

Step-by-step explanation:

Firstly, do 18/13.5 then multiply the answer by 21. This will give you the value of AC.

Next, use pythagoras theorem to find AD.

AD= square root of AC^2 + 18^2

Once you do this, divide the answer by 2.

Your final answer should be 16.6cm.
