The statement(s) that are true is that the measure of the reference angle is 45°.

<h3>What is the conversion of radians to degrees?</h3>

The conversion of an angle in radian to a degree can be determined by the multiplication of the given angle in radian by 180/π.

From the given information:

\mathbf{\theta = \dfrac{7 \pi}{4}}

To degrees, we have:

\mathbf{\theta = \dfrac{7 \pi}{4} \times \dfrac{180}{\pi}}

\mathbf{\theta =315^0}

A reference angle is an angle that measures the remaining distance (called the terminal distance) to the x-axis.

315° is in the 4th quadrant, i.e.

= 360° - 315°

= 45°

Therefore, the statement(s) that is true is:

  • The measure of the reference angle is 45°.
