Answer:
5
Step-by-step explanation:
Cause you can actually get multiple different answeres which you can make a statistical question on
The answer is A) √3
cot(-5π/6)=1/tan(-5π/6)
=1/tan(-(5π/6)
Use the property: tan(-x)=-tan(x)
=1/tan(5π/6)
-(1/tan(5π/6))
tan(5π/6)=-√3/3
-(1/-√3/3)
-(1/-√3/3)
=√3
4/3
Remember if two lines are perpendicular, the product of their slopes are -1
