Answer:

  1. Let the third angle in the triangle = z
  2. Now, angle z + 60° + 55° = 180°
  3. Angle z = 180-115° = 65°
  4. angle z = 65°
  5. Now, angle z + angle y = 180° (linear pair)
  6. 65° + y = 180°
  7. angle y = 180°-65°
  8. angle y = 115°
  9. Now again, angle X + angle y = 180° (linear pair)
  10. 115° + angle x = 180°
  11. angle X = 180°-115°
  12. Angle x = 65°

Part A

x = 180 - 55 - 60 (angle sum of a triangle, vertically opposite angles)

x = 65

I’ll find y anyways:

y = 180 - 65 (angles on a straight line)

y = 115
