Question

if pq || st, angle PQR = 110° and angle RST = 130°. Find angle QRS​

Answer 1

Step-by-step explanation:

QRS= 120° is the answer

Answer 2

Answer:

60 degrees

Step-by-step explanation:

Extend the line PQ to the right.

Now it becomes parallel to ST. Angle TSR + angle below it = 180 degrees as they are co interior angles.

Thus the angle below TSR is 50 degrees.

The point where PQ intersects RS is N for instance.

A triangle QRS is formed.

Angle QNR = 50 degrees as they are vertically opposite.

Angle NQR = 70 degrees as PQR and NQR form linear pair.

Thus angle QRS is 60 degrees  [by angle sum property of triangle]

Mark me brainliest for this effort.
