Question 2 (d) Find the angle represented by a. Making the figure again By corresponding angles ∠ a = Red angle Thus, we need to find red angle Now, applying linear pair in black line 67° + Red angle + Right angle = 180° 67° + Red angle + 90° = 180° (67° + 90°) + Red angle = 180° 157° + Red angle = 180° Red angle = 180° – 157° Red angle = 23° Thus, ∠ a = Red angle ∠ a = 23°
