A = √(15²-9²) = √(225-81) = √144 = 12
Answer:

Step-by-step explanation:
The identity you will use is:

So,


Now, using the difference of sin
Note: state that 

Solving the difference of sin:



Then,

Once

And,



Therefore,

I believe the answer is (-1,1) . The origin is the same as (0, 0) so I drew the line on a quick graph and if you are talking about distance, then the answer should be correct.
Hope this helped :)
