45º and -1.

Step-by-step explanation:

The angle is $\theta = \frac{7 \pi}{4}$ given in radians, but you want the angle in degrees.

$\frac{7 \pi}{4} \cdot \frac{180}{\pi} = \frac{1260}{4} = 315\º$

We got a Quadrant IV Angle.

Once the reference angle is the smallest angle that the terminal side of a given angle makes with the x-axis, we are talking about the angle $45\º$ .

Therefore, the reference angle is $45\º$ .

Also, the tangent of $\theta = \frac{7 \pi}{4}$ is -1
