![2+\cot A=1\implies \cot A=-1\implies \tan A=-1](https://tex.z-dn.net/?f=2%2B%5Ccot%20A%3D1%5Cimplies%20%5Ccot%20A%3D-1%5Cimplies%20%5Ctan%20A%3D-1)
This happens whenever
![A=\dfrac{3\pi}4](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B3%5Cpi%7D4)
or
![A=\dfrac{7\pi}4](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B7%5Cpi%7D4)
. More generally,
![\tan A=-1](https://tex.z-dn.net/?f=%5Ctan%20A%3D-1)
whenever you start with one of these angles and add any multiple of
![\pi](https://tex.z-dn.net/?f=%5Cpi)
, so the general solution would be
![A=\dfrac{3\pi}4+n\pi](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B3%5Cpi%7D4%2Bn%5Cpi)
, where
![n](https://tex.z-dn.net/?f=n)
is any integer. (Notice that when
![n=1](https://tex.z-dn.net/?f=n%3D1)
, you end up with
![\dfrac{7\pi}4](https://tex.z-dn.net/?f=%5Cdfrac%7B7%5Cpi%7D4)
.)
If it is bisector then it co ordinate points is in mid way(3,-2)
and it is perpendicular so its slope m2=-1/m1
where m1 is slope of another line passes through (4,1) nd (2,-5)
m1=-5-1/2-4=3
m2==-1/3
so equation of line is
y-3= -1/3(x+2)

Answer: $61.50
Step-by-step explanation:
To do this you need to first find 18% of 75 which is 13.5 or $13.50 and then subtract that from the original price being $75 and you get $61.50
HOPE THIS HELPS ^^
13/32=0.40625 that would be the answer to the problem
