4=2c-12-4
4=2c-16
20=2c
10=c
The answer would be an odd number, 111.
The first and crucial thing we want to take notice is that the lines DF and EG intersect at point H which creates 4 different triangles in the rhombus. The innermost angles of DGH and EFH are vertical angles and vertical angles are congruent. So if the angles of the triangles are congruent than the triangles themselves are congruent. This is supported by the vertical angles theorem.
Pretty sure the answer is A
Answer:
They are equal since they are both 90 degree angles.
