angles OBC and OCB = 24. angles BDC and BCD are 78. angle ABD = 30. angle BAO=?

Given the image, let's analyze and solve for the angle \(\angle BAO\).

### Given Information:
- \(\angle OBC = 24^\circ\)
- \(\angle OCB = 24^\circ\)
- \(\angle BDC = 78^\circ\)
- \(\angle BCD = 78^\circ\)
- \(\angle ABD = 30^\circ\)

### Step-by-Step Solution:

1. **Triangle \(OBC\):**
   - Since \(\angle OBC = \angle OCB = 24^\circ\), triangle \(OBC\) is an isosceles triangle.
   - Let \(\angle BOC\) be \(x\).
   - Using the angle sum property of triangles: 
     \[
     x + 24^\circ + 24^\circ = 180^\circ
     \]
     \[
     x = 180^\circ - 48^\circ = 132^\circ
     \]

2. **Triangle \(BDC\):**
   - \( \angle BDC = 78^\circ\) and \( \angle BCD = 78^\circ\).
   - Let \(\angle DBC = y\).
   - Again, by the angle sum property:
     \[
     y + 78^\circ + 78^\circ = 180^\circ
     \]
     \[
     y = 180^\circ - 156^\circ = 24^\circ
     \]

3. **Angle \( \angle BAO \):**
   - \(\angle ABD = 30^\circ\) is given.
   - \(\angle OBC = 24^\circ\).
   - \(\angle BAO = \angle ABD - \angle OBC\), since \(\angle BAO\) is the difference between \(\angle ABD\) and \(\angle OBC\).
     \[
     \angle BAO = 30^\circ - 24^\circ = 6^\circ
     \]

### Final Answer:
\(\angle BAO = 6^\circ\).
