Math Problem Statement

Find the value of x based on the inscribed angle and circle properties provided in the diagram.

Solution

To solve this problem, we need to determine the value of xx^\circ, and this involves applying properties of circles and angles.

Step-by-step Solution:

  1. Identify the key relationships:

    • The angle EAB=109\angle EAB = 109^\circ is an inscribed angle subtended by arc EBEB.
    • The angle BCD=x\angle BCD = x^\circ is also an inscribed angle subtended by the same arc EBEB.
    • In a circle, inscribed angles subtended by the same arc are equal.
  2. Apply the property of inscribed angles: EAB=BCD\angle EAB = \angle BCD Therefore: x=109x = 109^\circ

  3. Cross-check:

    • The angle 49.649.6^\circ is given, but it does not affect the calculation of xx^\circ because xx^\circ depends solely on the property of equal inscribed angles subtended by the same arc.

Final Answer:

x=109x = 109^\circ

Follow-up Questions:

  1. What are the properties of inscribed angles subtended by the same arc in a circle?
  2. How does the given angle 49.649.6^\circ relate to the diagram? Can it be used to verify xx^\circ?
  3. What is the relationship between central angles and inscribed angles subtending the same arc?
  4. If the circle were extended, how would tangent and secant properties apply to this scenario?
  5. How can you use this property to solve more complex circle problems involving overlapping arcs?

Tip:

Always remember that inscribed angles subtending the same arc are equal, regardless of where they are located on the circle!
