r and s cannot be parallel

Step-by-step explanation:

If a line intersects two parallel lines, then some special angles are formed between the parallel lines

From the given figure

∵ Line r and line s intersected by line m

∵ m∠1 = 111°

∴ The angle adjacent ∠1 must be 180 - 111 = 69° ⇒ linear pairs

∵ The angle of measure 69° and angle 5 are in the corresponding

   position

∴ m∠5 must be equal 69°

∵ m∠5 = 59° from the given

→ That means the lines cannot be parallel because the angles

   in the corresponding position are not equal in measures.

∴ Lines r and s can not be parallel
