In the given circle, angle CAD = 20 degrees. Find the value of x (angle CBD).

1. Identify the given information:

• Inscribed angle CAD = 20 degrees.
• Angle x (CBD) is to be found.

2. Recall the property of inscribed angles subtended by the same arc:

• Inscribed angles that subtend the same arc are equal.

3. Apply the property:

• Both angle CAD and angle CBD subtend the arc CD.
• Therefore, angle CBD = angle CAD.
• x = 20 degrees.
