You chose the right answer; DeltaMLK ~ DeltaMST

Explanation:

Since LK and ST are parallel, you can consider LM a transversal.
Therefore, their corresponding angles are congruent.
i.e. angleMSTcongangleL.

You can also say angleMcongangleM because an angle is always congruent to itself.

You can now say DeltaMLK is similar DeltaMST by the AA similarity postulate because two of their angles are congruent.
