FA FIFA Club World Cup 2018 16/01/2018 at 21:00tan(a)=12⇔a=26,5605118
⇒tan(90−2a)=tan(90−2⋅26,56505118)=34

Alone 16/01/2018 at 13:10Dao Trong Luan:Why? tan(a)=\(\dfrac{1}{2}\) can \(\Rightarrow a=26,5605118\)
This is you use calculator for calculate

AL 16/08/2017 at 15:58Use AM-GM's ineq:
\(\dfrac{b+c}{\sqrt{a}}+\dfrac{c+a}{\sqrt{b}}+\dfrac{a+b}{\sqrt{c}}\ge\dfrac{2\sqrt{bc}}{\sqrt{a}}+\dfrac{2\sqrt{ca}}{\sqrt{b}}+\dfrac{2\sqrt{ab}}{\sqrt{c}}\)
\(=\left(\sqrt{\dfrac{bc}{a}}+\sqrt{\dfrac{ca}{b}}\right)+\left(\sqrt{\dfrac{ca}{b}}+\sqrt{\dfrac{ab}{c}}\right)+\left(\sqrt{\dfrac{ab}{c}}+\sqrt{\dfrac{bc}{a}}\right)\)
\(\ge\sqrt{a}+\sqrt{b}+\sqrt{c}+\sqrt{a}+\sqrt{b}+\sqrt{c}\)
\(\ge\sqrt{a}+\sqrt{b}+\sqrt{c}+3\sqrt[3]{abc}\)\(=\sqrt{a}+\sqrt{b}+\sqrt{c}+3\)

Help you solve math 28/08/2017 at 15:061st way :10 + 20 + 60 + 40 + 80 + 90
=(1 + 2 + 6 + 4 + 8 + 9) x 10
=30 x 10
=300
2nd way :10 + 20 + 60 + 40 + 80 + 90
=(10 + 90) + (20 + 80) + (60 + 40)
=100 + 100 + 100
=100 x 3
=300
