The missing values if both triangles are congruent are:
x = 3
EG = 10
FG = 8
EF = 6
What are Congruent Triangles?
If two triangles are congruent, therefore, their corresponding parts would be congruent based on the CPCTC theorem.
EG is congruent to FE because both triangles are congruent.
EG = AC
7x - 11 = 2x + 4
Find x
7x - 2x = 11 + 4
5x = 15
x = 3
EG = 7x - 11 = 7(3) - 11 = 10
FG = 3x - 1 = 3(3) - 1 = 8
EF = AB = 5x - 9 = 5(3) - 9 = 6
