Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .
The coordinates of Ф are x ,y in rectangular form ==> so:
tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1
Hence y = - x
All I know is x is 81 degrees
Answer:
f(x)=-3x+14
Step-by-step explanation:
y +1=-3(x–5)
y +1=-3x+15
y= -3x+15-1
f(x) = -3x + 14
