Answer:

∠5 = 55°

Step-by-step explanation:

Since l and m are parallel lines, then ∠5 and ∠1 are same- side interior angles and are supplementary, thus

∠1 + ∠5 = 180°, that is

125° + ∠5 = 180° ( subtract 125° from both sides )

∠5 = 55°

Answer:

55 degrees.

Step-by-step explanation:

m < 2 = 180 - 125 = 55 degrees (adjacent angles).

m < 5 = m < 2 (alternate angles).

Therefore m < 5 = m < 2  = 55 degrees.
