Vì BM là p/g của \(\widehat{ABC}\) nên \(\widehat{B_1}=\widehat{B_2}=\dfrac{\widehat{ABC}}{2}\)

Vì CM là p/g của \(\widehat{ACB}\) nên \(\widehat{C_1}=\widehat{C_2}=\dfrac{\widehat{ACB}}{2}\)

Ta có:\(\widehat{C_1}+\widehat{B_2}+\widehat{BMC}=180^o\) (tổng ba góc của một tam giác)

          \(\widehat{C_1}+\widehat{B_2}=180^o-118^o\)

          \(\widehat{C_1}+\widehat{B_2}=62^o\)

          \(\Rightarrow\dfrac{\widehat{ABC}}{2}+\dfrac{\widehat{ACB}}{2}=62^o\)

         \(\Rightarrow\widehat{ABC}+\widehat{ACB}=124^o\)

   Ta có:\(\widehat{CAB}+\widehat{ABC}+\widehat{BAC}=180^o\) (tổng ba góc của một tam giác)

             \(124^o+\widehat{BAC}=180^o\)

            \(\widehat{BAC}=56^o\)

 

Ta có: \(\widehat{BMC}+\widehat{MBC}+\widehat{MCB}=180^0\)

\(\Leftrightarrow\left(\widehat{ABC}+\widehat{ACB}\right)\cdot\dfrac{1}{2}=62^0\)

\(\Leftrightarrow\widehat{ABC}+\widehat{ACB}=124^0\)

\(\Leftrightarrow\widehat{BAC}=56^0\)
