Isosceles X B3Dce1
1. **State the problem:** We have an isosceles triangle with one angle given as 104° and the two base angles equal, one labeled as $92 - 2x$ degrees. We need to find the value of $x$.
2. **Recall the properties of an isosceles triangle:** The two base angles are equal. The sum of all angles in any triangle is 180°.
3. **Set up the equation:** Let the two equal base angles be $92 - 2x$ each. The top angle is 104°. So,
$$104 + (92 - 2x) + (92 - 2x) = 180$$
4. **Simplify the equation:**
$$104 + 92 - 2x + 92 - 2x = 180$$
$$104 + 184 - 4x = 180$$
$$288 - 4x = 180$$
5. **Solve for $x$:**
$$-4x = 180 - 288$$
$$-4x = -108$$
$$x = \frac{-108}{-4} = 27$$
6. **Final answer:**
$$\boxed{27}$$
