Answer: x=30 degrees

Step-by-step explanation:

Reason: Triangle Congruency

  1. ΔABC ≅ ΔDEC --> this means that ∠A≅∠D, ∠B≅∠E, ∠C≅∠C --> definition of congruent triangles
  2. 55°+65°+2x= 180° --> CPCTC (Corresponding parts of congruent triangles are congruent) and sum of angles in triangle
  3. x= 30 degrees--> Algebra
X=30 degrees becuase of the algebraic solution
