Question 5 In Fig. 5.34, AB is parallel to CD and CD is parallel to EF. Also, EA is perpendicular to AB. If ∠BEF = 55°, find the values of x and y. Taking parallel lines CD and EF, with blue line as transversal ∠ y and 55° are are interior angles on same side of transversal ∠ y + 55° = 180° ∠ y = 180° – 55° ∠ y = 125° Taking parallel lines AB and CD, with blue line as transversal ∠ x and ∠ y are corresponding angles ∠ x = ∠ y ∠ x = 125°
