x等于多少度---Triangle Problem 1 **Image Description:** * **Type:** Geometric figure (Triangle). * **Main Elements:** * A triangle ABC is shown, with vertex C at the top and vertices A and B at the bottom. A is on the left, B is on the right. * A point D is located on side AC. * A point E is located on side BC. * Line segments AE, BD, and DE are drawn. AE and BD intersect inside the triangle. * **Angles:** * Angle at vertex A, formed by sides AC and AB (∠CAB), is indicated as 70 degrees. * Angle at vertex B, formed by sides BA and BC (∠CBA), is indicated as 60 degrees. * Angle formed by segments AB and AE (∠BAE) is indicated as 10 degrees. This angle is part of ∠CAB. * Angle formed by segments BA and BD (∠ABD) is indicated as 20 degrees. This angle is part of ∠CBA. * Angle formed by segments ED and EA (∠DEA) is indicated as 'x'. **Extracted Textual Content:** * **Title:** Triangle Problem 1 * **Labels:** Points A, B, C, D, E. Angle labels 70°, 60°, 10°, 20°, x. **Problem Statement:** (Based on the diagram, the implied question is to find the value of x). No explicit question is stated in text. **Options:** No options are provided.
