Answer:

\checkmark \sin\theta=-\frac{\sqrt{2}}{2}

\checkmark \tan \theta = -1

\checkmark The measure of the reference angle is 45^{\circ}

Step-by-step explanation:

The reference angle of an angle is the magnitude of the smallest angle it makes with the x-axis. In this case, we have 360-315=\boxed{45^{\circ}} (*Note: \frac{7\pi}{4}=315^{\circ}, use \pi=180^{\circ} to convert to degrees)

Step-by-step explanation:

Convert 7π/4 to degrees

You'll have 315°

Reference angle is the angle that a given angle makes with the abscissa or x-axis.

360-315 = 45°

THE MEASURE OF THE REFERENCE ANGLE IS 45°

C and D are correct also
