Given:-
AB || CD, ∠APE= 45°( Let the middle curve transversal be E) and ∠CQE= 30°
To Find:-
Measurement of ∠x
Construction:-
Draw a line YZ parallel to AB and CD
Solution:-
✒ ∠APE= 45° ( Given)
AB || YZ ( From Construction)
therefore,
✒ ∠APE= ∠PEZ ( Alternate Interior angle)
therefore, ∠PEZ= 45°______(1)
Similarly,
✒ ∠COE= ∠QEZ ( Alternate Interior angle)
therefore, ∠QEZ = 30°______(2)
From eq. (1) and (2).
✒∠ PEZ + ∠QEZ + ∠x = 360° ( angle from a point)
✒ 45°+ 30° + ∠x = 360°
✒ 75°+ ∠x = 360°
✒ ∠x = 360° - 75°
∠x = 285°
Hope it helps you...!!!!
