What is the length of $\overline{AB}?$ (marked in red)

\frac{24 \cdot \sin 18^\circ}{\tan(57^\circ)}

\frac{12 \cdot \cos 57^\circ}{\tan(18^\circ)}

24 \cdot \sin 18^\circ \cdot \tan(57^\circ)

12 \cdot \sin 57^\circ \cdot \tan(18^\circ)

Earlier, we used angles to help solve for side lengths of right triangles. Let's see if we can reason with side lengths to solve for angles.

What is $\delta$ in radians?
