(-5,-2) is in the 3rd quadrant where sines & cosecants are always negative
cotangents always positive
cotT= adjacent side over opposite side = x/y = -5/-2 = 5/2 = 2.5 = 2 1/2
sinT = opposite side over hypotenuse = y/h =-2/sqr(x^2+y^2) =-2/sqr(25+4)=-2/sqr29
= -2sqr29/29
cscT = 1/sinT = -sqr29/2

Isn't the opposite side -2?

Know the Unit Circle, CAST, Pythagorean Theorem to find the answer.
