\[
x=[?]
\]
Solution
Solution Steps
Step 1: Identify the given information
We are given two triangles inscribed in a circle. Both triangles share a common side of length 5. The angles between the common side and the other two sides are both 30°. One triangle has a side length of 2, and the other has a side length of x.
Step 2: Recognize triangle congruence
Since both triangles share a common side and have the same angles adjacent to that side (30°), they are congruent by the Side-Angle-Side (SAS) theorem.
Step 3: Determine the value of x
Because the triangles are congruent, their corresponding sides are equal. Therefore, x = 2.
