13. [2/4 Points] DETAILS PREVIOUS ANSWERS OSCAT1 7.3.164. MY NOTE Find the reference angle. 225° 45 ° Find the quadrant of the terminal side of the given angle. Quadrant I Quadrant II Quadrant III Quadrant IV Find the sine and cosine of the angle. If the angle is not one of the angles on the unit circle, use a calculator and round to three decimal places. \sin(225^\circ) = -0.707 \cos(225^\circ) = -0.707 The point $(x, y)$ that is on the terminal side of angle $t$ in standard position corresponds to the unit circle point $(\cos(t), \sin(t))$. Draw the given angle $t$ in standard position. How is the angle's reference angle related to the terminal side of angle $t$ and the horizontal axis? How are the values of the sine and cosine of the reference angle along with the sign of the coordinates of points on the terminal side of angle $t$ useful for stating the exact values of $\sin(t)$ and $\cos(t)$?
