Answer:

315°

Step-by-step explanation:

  • ∠HCG = 180° - 60° - 75° = 45°
  • ∠DCH = 360° - 180° - 45° = 135°

Finding m∡DHE

  • ∠DCH + ∠HCG + ∠GCF + ∠ECF
  • 135° + 45° + 75° + 60°
  • 180° + 135°
  • 315°

Answer:

m∡DHE = 315°

Step-by-step explanation:

Angles around a point always add up to 360°.

⇒ m∡DHE = 360° - m∡ED

                  = 360° - 45°

                  = 315°
