Answer:

45º and -1.

Explanation:

The angle is
$\theta = (7 \pi)/(4) $ given in radians, but you want the angle in degrees.


$(7 \pi)/(4) \cdot (180)/(\pi) = (1260)/(4) = 315\º$

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 = (7 \pi)/(4) $ is -1
