Angles DEF and GEH have the following measures:

m∠DEF = (x − 14)°, m∠GEH = (3x + 16)°.

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.
