In the image, there appears to be a diagram with intersecting lines, angles labeled with variables such as $a$, $b$, $c$, $d$, $e$, $f$, and specific angle measures like $20^\circ$ and $10^\circ$.

Since intersecting lines create vertically opposite angles and supplementary angles (angles adding up to $180^\circ$), we can apply these properties to find the unknown angles.

Could you confirm if the goal is to find all the unknown angles in the diagram? Also, is there more information missing from the question, or would you like me to proceed with what we have?
