In this geometric diagram, we have:

• Line $AB$, $CD$, and $EF$ forming various angles.
• The triangle $BCE$, where we need to solve for $x^\circ$.
• Given that:
  • $\angle BCD = 93^\circ$
  • $\angle ABC = 2x^\circ$
  • $\angle EBC = x^\circ$

Steps to Solve:

1. Identify Key Angles: The sum of angles in a triangle is always $180^\circ$. In triangle $BCE$: $\angle BCE + \angle EBC + \angle BEC = 180^\circ$ Substituting the given values: $93^\circ + x^\circ + 2x^\circ = 180^\circ$

2. Solve for $x$: Simplify the equation: $93^\circ + 3x^\circ = 180^\circ$ $3x^\circ = 180^\circ - 93^\circ$ $3x^\circ = 87^\circ$ $x^\circ = \frac{87^\circ}{3}$ $x^\circ = 29^\circ$

Thus, $x = 29^\circ$.

Follow-up questions:

1. How is the sum of angles in a triangle derived?
2. What would happen if $\angle BCD$ was different?
3. Can we generalize this process for other triangle configurations?
4. What is the significance of supplementary angles in this diagram?
5. How could we use trigonometric ratios if the sides of the triangle were known?

Tip: In any triangle, the sum of interior angles is always 180°, which is a fundamental rule in Euclidean geometry.
