Câu hỏi: Cho \(\Delta ABC = \Delta D{\rm{EF}}\). Biết \(\widehat A + \widehat B = {130^0};\widehat E = {55^0}\). tính các góc \(\widehat A;\widehat C;\widehat D;\widehat F\)

A. \(\widehat A = \widehat D = {75^0};\widehat C = \widehat F = {60^0}\)

B. \(\widehat A = \widehat D = {50^0};\widehat C = \widehat F = {75^0}\)

C. \(\widehat A = \widehat D = {75^0};\widehat C = \widehat F = {50^0}\)

D. \(\widehat A = \widehat D = {75^0};\widehat C = \widehat F = {55^0}\)
