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 = =
With this information, this angle can be in the second and in the third quadrangle.
sin Ф can be or sin Ф =
tan Ф or tan Ф =
csc Ф = or csc Ф =
The first one is x^2 -9x +20
The second one is x^2 -12x +20
The third one is x^2 +x -20
The fourth one is x^2 - 8x -20
