Answer 1

Answer:

R.E.F image

Given: PQ∥RS

since, PQ∥RS

By applying alternate

angle property

∠PQR=∠QRS=55 o(1)and ∠MLR+∠SRL=180o

therefore, LM∥RS (2)

(sum of interior angle property)

Therefore, from eq.

(1) and (2)

PQ∥LM

Therefore, from sum of interior angle property

the angle between the lines PQ and LM=180

o
