Answer:
A. 1
Explanation:
Given the point P(-5,5), this falls in the second quadrant.
Accoording to pythagoras theorem;
r^2 = x^2 +_ y^2
r^2 = (-5)^2 + 5^2
r^2 = 25 + 25
r^2 = 50
r = \sqrt[50]
r = 5\sqrt[5]
Get cot theta;
cot theta = 1/tan theta
in the second quadrant, tan theta = y/-x
tan theta = 5/-(-5)
tan theta = 5/5
tan theta = 1
Recall that cot theta = 1/tan theta
cot theta = 1/1
cot theta = 1
Hence the correct option is A
