High School Math - Hinge Theorem to Solve for x in Angle Inequality

Keywords: Hinge Theorem, SAS Inequality, angle inequality, solving for x, high school math
This problem uses the Hinge Theorem (SAS Inequality) to determine the inequality for \(x\), given two triangles with congruent sides (length 7) and different included angles (\(10^\circ\) and \(\frac{1}{8}x^\circ\)) and third sides (13 and 21). The solution is \(x > 80\).
