Quadrant III (180° to 270°): Tangent is ALWAYS positive! Immediately eliminate A and B.
The condition \(\pi < \theta < \frac{3\pi}{2}\) places \(\theta\) in Quadrant III, where cosine and sine are negative, and tangent is positive. Using \(\sin^2 \theta + \cos^2 \theta = 1\), \(\sin \theta = -\sqrt{1 - (-5/13)^2} = -\frac{12}{...
