In two triangles with top angles of 58°, 58°, and a common bottom angle of 60°, the corresponding sides are 4x - 6 and 3x + 11. Solving 4x - 6 = 3x + 11 yields x = 17.
Let's break it down step by step:
1. Top angles of both triangles: 58° and 58°.
2. Bottom angle of both triangles: 60°.
3. One side of the first triangle: 4x - 6.
4. Corresponding side of the second triangle: 3x + 11.
Step 1: Set up an equation based on the sum of interior angles in a triangle.
58 + 58 + 60 = 180
Solving for the remaining angle:
176 + 60 = 236
So, the third angle is 180 - 236 = -56. However, since angles cannot be negative, there might be an issue with the given angles. Let's assume the given angles are correct.
Step 2: Set up an equation based on the side lengths of the triangles.

Solving for x:
![\[4x - 3x = 11 + 6\]\[x = 17\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/jehp0yxyaqfgtzr524gferw21ud30u0gme.png)
So, the value of x is 17.
