Answer:

Angle ABC = 30°

Step-by-step explanation:

  1. Construct a ray AB, horizontally.
  2. Take a compass, keep the pointy edge on the origin of the ray and make an arc passing through AB.
  3. Mark the point where the arc cuts AB as X
  4. Place the pointy edge of the compass on X, draw another arc through the existing arc.
  5. Mark the point where on arc cuts the other arc as Y.
  6. Now from the origin of AB through the point Y draw a straight line.
  7. The angle thus formed is 60°.
  8. Now make arcs keeping the compass on X and Y.
  9. Mark the point where these two arcs meet as Z.
  10. Now from the origin of AB through the point Z draw a straight line.
  11. The angle formed in this process is a 30°.
