Question

i. Three angles of a quadrilateral PQRS are angle P=70 degrees, angle, Q=82 degrees
and angle R= 85 degrees find angle S.​

Answer 1

Answer:

Angle sum property of Quadrilateral = 360•

P + Q + R + S = 360•

70 + 82+ 85 +S = 360 •

237+S = 360

S = 360- 237

S =123 •

Answer 2

Answer:

Given = p = 70°

Q = 82°

R = 85°

S = ?

To find angle s

Angle sum property of quadrilateral

P + Q + R + S = 360°

70° + 82° + 85° + S = 360°

273° + S = 360°

S = 360° - 273° = 123°

S = 123°
