Solve for x

On an educational website, the following transcription and explanation can help in understanding the problem presented: --- ### Problem 4: Solve for \( x \) #### Description: The problem involves a triangle with a perpendicular line segment dividing the base into two segments. Here's the detailed explanation: 1. **Triangle Structure**: - The base of the larger triangle is given as 29 units. - The two sides of the larger triangle are given as 20 units and 21 units respectively. 2. **Internal Triangle Details**: - A perpendicular line segment from the vertex opposite the base to the base divides the base. - This line segment creates two right triangles within the larger triangle. - The length of the perpendicular line segment is labeled as \( x \). #### Diagram Explanation: - The diagram shows an isosceles triangle split into two right triangles by a perpendicular bisector from the vertex perpendicular to the base. - The sides of the triangles are labeled. The hypotenuses of the right triangles are 20 and 21 units, respectively. - The entire base of the larger triangle is labeled as 29 units. - The perpendicular line segment from the vertex creating the right angle with the base is labeled as \( x \). To solve for \( x \), understanding and applying the properties of right triangles and the Pythagorean theorem will be crucial.
