Solution
ABCD and AEFG are two parallelograms as shown below:

Since ABCD is a parallelogram, with ∠C = 58°
We know that the opposite angles of a parallelogram are equal.
Therefore,
∠A = ∠C
∠A = 58°
Similarly, AEFG is a parallelogram, with ∠A = 58°
We know that the opposite angles of a parallelogram are equal.
Therefore,
∠F = ∠C
∠F = 58°
Hence, the required measure for ∠F is 58°.
