Final answer:
In a rectangle, opposite angles are congruent. Therefore, ∠MBC = ∠CDA = 47 degrees. Using this information and the fact that the sum of angles in a triangle is 180 degrees, we can solve for x.
Step-by-step explanation:
In a rectangle, opposite angles are congruent. So, ∠MBC = ∠CDA = 47 degrees.
Since ABCD is a rectangle, ∠CAB = 90 degrees. Therefore, ∠MCA = 90 - ∠MCD = 90 - 47 = 43 degrees.
Since the sum of the angles in a triangle is 180 degrees, we have ∠MCA + ∠CAB + ∠BCA = 180 degrees. Substituting the values, we get 43 + 90 + x = 180. Solving for x, we find that x = 47 degrees.
