If you draw a simple diagram you can see that point to form a right angle ACB, C must be at (3,0).
First add 15 to both sides:
2n = 68
Then divide each side by two.
n = 34
I believe that the scale factor is 7. Hope I helped!
Answer:
Step-by-step explanation:
From the figure attached,
1). Sin(D) =
= 
= 
= 
2). Cos(D) = 
= 
= 
= 
3). tan(D) = 
= 
= 
= 
4). sin(F) = 
= 
= 
= 
5). cos(F) = 
= 
= 
= 
6). tan(F) = 
= 
= 
=
