The formulat for finding the slop is
m = (y2 - y1)/(x2 -x1)
so if we put the values of our two given points
m = (-13 -12) / (5 - 5) = -25/0 = undefined
so our slop is undefined which means it is a vertical line
![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)
.)
Answer:
its 90
Step-by-step explanation:
Answer:
x = -6
Step-by-step explanation:
-4x - 3(2x + 8) = 36
-4x - 6x - 24 = 36
-10x = 60
-x = 6
x = -6
