Answer 1

Step-by-step explanation:

Angle ABQ = 60°

So Angle PQB = 180° - 60° ( Co-interior angles)

= 120°

So Angle RQS = 120° (Vertically Opposite angles)

Angle QRS + Angle RQS + Angle QSR = 180°

(By angle sum property of a triangle)

=> 30° + 120° + Angle QSR = 180°

=> 150° + Angle QSR = 180°

=> Angle QSR = 180° - 150°

=> Angle QSR = 30°

Therefore Angle QSR is 30°.

Step-by-step explanation:

Angle ABQ = 60°

So Angle PQB = 180° - 60° ( Co-interior angles)

= 120°

So Angle RQS = 120° (Vertically Opposite angles)

Angle QRS + Angle RQS + Angle QSR = 180°

(By angle sum property of a triangle)

=> 30° + 120° + Angle QSR = 180°

=> 150° + Angle QSR = 180°

=> Angle QSR = 180° - 150°

=> Angle QSR = 30°

Therefore Angle QSR is 30°.
