ý bạn là \(\widehat{B}=35^0;\widehat{K}=100^0?\)
\(\Delta ABC=\Delta DHK\\ \Rightarrow\left\{{}\begin{matrix}\widehat{B}=\widehat{H}=35^0\\\widehat{C}=\widehat{K}=100^0\end{matrix}\right.\\ \widehat{A}+\widehat{B}+\widehat{C}=180^0\\ \Rightarrow\widehat{A}=180^0-135^0=45^0\\ \Rightarrow\widehat{D}=\widehat{A}=45^0\left(\Delta ABC=\Delta DHK\right)\)
