Where the line segment A starts is home
The answer is -48 because there is a 4/8 difference and that equals -24. Multiply by 2 and you have your answer.
You can't exactly get the trigonometric functions using a point unless it's a vector,
so tanx = -8/-6 = 4/3 and from it we can get the other functions
sinx = -4/5
cosx = -3/5
secx = -5/3
cscx = -5/4
cotx = 3/4
3 7 is the answer I hope this helps
