Property 3
\(\alpha=90^\circ\Rightarrow a^2=b^2+c^2\)
\(\alpha>90^\circ\Rightarrow a^2>b^2+c^2\)
\(\alpha<90^\circ\Rightarrow a^2<b^2+c^2\)
1.
\(\alpha<90^\circ\)
\(\Rightarrow ?<x<?\)
2.
\(\Rightarrow ?<x<?\)
3.
\(x\in\mathbb{N}\)
\(\Rightarrow\max\left(x\right)=?\)
4.
\(x\in\mathbb{Z}\)
\(\alpha<90^\circ\)
\(\beta<90^\circ\)
\(\Rightarrow\sum\limits x=?\)
5.
\(x\in\mathbb{Z}\)
\(m\left(\widehat{BDC}\right)<45^\circ\)
\(\Rightarrow\max\left(x\right)=?\)
6.
\(\Rightarrow ?<x<?\)
7.
\(x\in\mathbb{Z}\)
\(\Rightarrow\max\left(x\right)+\min\left(x\right)=?\)
