Answer:

x=7°

Explanation:

The figure is a triangle.

1. Triangles's angles add up to 180°.

2. We know that 1 angle measures 104°, so the remaining 2 angles add up to 76°. It is an isosceles triangle, so both of the remaining 2 angles have equal measures.

3. 76÷2=38°.

4. 9x-25°=38°

5. 63°-25°=38°

6. 9x=63°

7. x=7°

Step by step explanation above. Hope it is correct!
