Answer:
x=7°
Step-by-step 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!
