Answer
Sine and cosecant are positive. All others are negative.
Work Step by Step
A $125^{\circ}$ is in quadrant II. In the second quadrant, $x$ is negative but $y$ and $r$ are positive.
$\implies \sin\theta=\frac{y}{r}=\text{positive}$
As $\csc\theta=\frac{1}{\sin\theta}$, $\csc\theta$ is also positive.
$\cos\theta=\frac{x}{r}=\text{negative}$
Secant which is the inverse of cosine is also negative.
$\tan\theta=\frac{y}{x}=\text{negative}$
$\cot\theta=\frac{x}{y}=\text{negative}$
