-Ta có: 2 điểm vẽ 1 đt
=> n điểm sẽ vẽ đc n-1 đt
-Lược bỏ những đt trùng nhau
=>Số đt có là: [n(n-1)]/2(đoạn thẳng)
b/
-Ta có: \(\hept{\begin{cases}5\widehat{B}+\widehat{A}=180^o\left(1\right)\\2\widehat{B}+\widehat{A}=90^o\left(2\right)\end{cases}}\)
-Lấy: (1) trừ (2) vế theo vế.
-Ta được: \(\hept{\begin{cases}3\widehat{B}=90^0\\\widehat{A}=90^0-2\widehat{B}\end{cases}\Leftrightarrow\hept{\begin{cases}\widehat{B}=30^0\\\widehat{A}=90^0-60^0=30^0\end{cases}}}\)
-Vậy: \(\widehat{A}=\widehat{B}=30^0\)

Ta có: 2(R+D)=260 (1)
R+14=D-20-> R=D-34 (2)
Thay(2) vâò (1) ta đc: 2(D-34+D) =260
<=> 4D-68=260
<=> 4D=328
<=> D=82
=> R= 48
S=DR=82.48=3936m2 = 0,3936 ha
