if u givee write answer i give u 20 points ​

Answer 1

Answer:

x = 120°

Step-by-step explanation:

Sum of all angles of the quadrilateral = 360°

∠P + ∠Q + ∠R + ∠S = 360°

50° + 40° + 30° + ∠S = 360°

120° + ∠S = 360°

∠S = 360° - 120°

∠S = 240°

∠S + x = 360°

240° + x = 360°

x = 360 - 240°

x = 120°
