Consider circle A in the diagram below where the m∠DCG=25∘ and mCF^=60∘ and prove that m∠EDF=55∘ . Given that m∠DCG=25∘ , this angle intercepts arc DG^ which makes mDG^=_ , this means that mED^=130∘ as EG^ is a diameter. Select a Value ∠CED intercepts CFD^ , which makes m∠CED=_ . Select a Value ∠ECD intercepts ED^ which makes m∠ECD=_ . Select a Value ∠CDF intercepts CF^ which is 60∘ , making m∠CDF=30∘ . Using the triangle sum theorem, m∠EDC=_ , and using Angle addition postulate the m∠EDF=55∘ . Select a Value
