Since triangles ABC and DEF are congruent, the measures of their corresponding angles are equal. Therefore, we have:
\[
m \angle A = m \angle D
\]
According to the problem, we are given:
\[
m \angle A = x + 27
\]
\[
m \angle D = 2x
\]
Setting these two expressions equal to each other since the angles are congruent:
\[
x + 27 = 2x
\]
Now, we can solve for \(x\):
1. Subtract \(x\) from both sides:
\[
27 = 2x - x
\]
\[
27 = x
\]
2. Now that we have found \(x\), we can find the measure of angle A:
\[
m \angle A = x + 27 = 27 + 27 = 54
\]
3. Also, we can find the measure of angle D:
\[
m \angle D = 2x = 2 \times 27 = 54
\]
Thus, the final answers are:
Part 1:
\[
m \angle A = 54
\]
Part 2:
\[
m \angle D = 54
\]
