Question

Q . 4. In a quadrilateral PQRS, ∠ = 50°, ∠ = 60°, ∠ = 60°. Find ∠.​

Answer 1

Answer:

190°

Step-by-step explanation:

Sum of all angles of a quadrilateral is 360°.

Let last angle be x

50° + 60° + 60° + x = 360°

170° + x = 360°

x = 360° - 170°

x = 190°

Answer 2

Step-by-step explanation:

In any quadrilateral sum of all the angles =360°

Therefore

∠P+∠Q+∠R+∠S=360°

50°+60°+60°+∠S=360°

170°+∠S=360°

∠S=360°-170°. ( Transposition)

∠S=190°
