Rút gọn giúp mình với  

\(\dfrac{24-9\sqrt{3}}{3-\sqrt{3}}\)

Tính: \(\dfrac{2\left(\sqrt{6-2\sqrt{5}}+6-2\sqrt{5}+1\right)}{\sqrt{6-2\sqrt{5}}}\)

Giúp mình vs, tks nhiều 🌹

Tầm 2 tháng trước e có đóng góp môn sử giờ có được duyệt kh ạ? 

Ta có \(\widehat{A}+\widehat{B}+\widehat{C}+\widehat{D}=360^0\)

\(\Rightarrow\widehat{C}+\widehat{D}=360^0-\left(\widehat{A}+\widehat{B}\right)=360^0-\left(60^0+100^0\right)=200^0\)

\(\widehat{D}=\dfrac{200^0-40^0}{2}=80^0\)

\(\widehat{C}=\widehat{D}+40^0=80^0+40^0=120^0\)
