Angles DEF and GEH have the following measures:
m2DEF=(x-18), mzGEH= (3x + 4)

Part A: If angle DEF and angle GEH are complementary angles, find the value of x. Show every step of your work.

Part B: Use the value of x from

Part A to find the measures of angles DEF and GEH. Show every step of your work.

Part C: Could the angles also be vertical angles? Explain.
