Answer:

The answer to your question are  A and D

Step-by-step explanation:

If cos Ф = -2/3 means that

adjacent side = -2 and hypotenuse = 3

Opposite side = [tex]\sqrt{3^{2} - (-2)^{2}}[/tex] = [tex]\sqrt{5}[/tex]

With this information, this angle can be in the second and in the third quadrangle.

sin Ф can be  [tex]\sqrt{5}/3[/tex]       or   sin Ф = [tex]\frac{- \sqrt{5}}{3}[/tex]

tan Ф[tex]-\frac{\sqrt{5}}{2}[/tex]                       or  tan Ф = [tex]\frac{\sqrt{5}}{2}[/tex]

csc Ф = [tex]\frac{3}{\sqrt{5}}[/tex]                      or  csc Ф = [tex]\frac{-3}{\sqrt{5}}[/tex]
