Question

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 S= 123°

Step-by-step explanation:

Given, angle P= 70°

angle Q= 82°

and angle R= 85°

We know that, sum of four angles of a quadrilateral is 360°

Therefore,

angle P + angle Q + angle R + angle S=360°

70° + 82° +85° + angle S=360°

237 + angle S= 360°

angle S= 360°- 237°

angle S= 123°...
