Answer»

Here, Angle RQD = 25°

so, angle ARQ = 25° . (Alt. INTERIOR angles)

Angle CQP = 60°

Angle QPE = 180° - 60° = 120° . (Sum of co-interior angles = 180°)

Give, PQ||RS

THEREFORE, Angle QPE = Angle ARS = 120° . (Same angles on a parallel line)

Therefore, Angle QRS

= Angle ARQ + Angle ARS

= 25° + 120°

= 145°
