How to interpret making "angles of $\mathbf {30}^\circ$ and $\mathbf{60}^\circ $ with the horizontal line parallel to the ground"? > A rope dancer was walking on a loose rope tied to the top of two equal posts of height $9$m. When he was $\mathbf 3$m above the ground, it was found that the stretched pieces of the rope made angles of $\mathbf {30}^\circ$ and $\mathbf{60}^\circ $ with the horizontal line parallel to the ground . Find the length of the rope. I could not understand the given highlighted condition and could not figure out the diagram. can anyone help with this?

This is how I understand it. I drew a picture.
