Question

3. In trapezium PQRS, PQ || RS. If angle P = 150° then find angle S​

Answer 1

sum of angle p and s is 180 so 180-150 is angle 30

Answer 2

The value of angle S is 30°.

Step-by-step explanation:

Given data

• PQRS is a trapezium.

       ∠P = 150°

       PQ║RS

      Means SP and QR will be traversal line.

• We know that sum of co- interior angle is 180°.Means

• ∠Q + ∠R =180° (Because sum of co- interior angle is 180°)

       and

      ∠S + ∠P =180°  (Because sum of co- interior angle is 180°)

       ∠S + 150° =180°

       ∠S =180°-150°

       ∠S = 30°= This is value of angle S.
