Answer:

  • 77 degrees

Step-by-step explanation:

According to the triangle angle sum theorem, interior angles sum to 180 degrees:

  • x + 56 + 47 = 180
  • x + 103 = 180
  • x = 180 - 103
  • x = 77

Answer: Equal/same which is 77 degrees

Explanation: This is because if two of the angles of the triangles are same then the third angle will also be the same. This can be showed by a proof like:

You know that the sum of a triangle's angles are 180 degrees. So If you add 56+47 the remaining angle value is same for both triangle ABC and DEF. The remaining angle is 77 degrees.
