with working please all solutions

Answer 1

Answer:

55°

Step-by-step explanation:

Given, in the figure, PQ||SR.

According to a theorem,

if two lines are parallel then pair of angles give 180° after sum.

So, let angle R measures x degrees. Then,

angle Q+angle R = 180°

=> 125°+x = 180°.

=> x = 180°-125° = 55°
