bài 2:

ta có: AB<AC<BC(Vì 3cm<4cm<5cm)

=> góc C>góc A> góc B (Các cạnh và góc đồi diện trong tam giác)

Bài 3:

*Xét tam giác ABC, có:

       góc A+góc B+góc c= 180 độ( tổng 3 góc 1 tam giác)

hay góc A+60 độ +40 độ=180độ

  => góc A= 180 độ-60 độ-40 độ.

  => góc A=80 độ

Ta có: góc A>góc B>góc C(vì 80 độ>60 độ>40 độ)

        => BC>AC>AB( Các cạnh và góc đối diện trong tam giác)

a: Áp dụng tính chất của dãy tỉ số bằng nhau, ta được:

\(\dfrac{a}{1}=\dfrac{b}{3}=\dfrac{c}{5}=\dfrac{a+b+c}{1+3+5}=\dfrac{180}{9}=20\)

Do đó: a=20; b=60; c=100

Vậy: ΔABC là tam giác tù

3:

góc C=90-50=40 độ

Xét ΔABC vuông tại A có sin C=AB/BC

=>4/BC=sin40

=>\(BC\simeq6,22\left(cm\right)\)

\(AC=\sqrt{BC^2-AB^2}\simeq4,76\left(cm\right)\)

1:

góc C=90-60=30 độ

Xét ΔABC vuông tại A có

sin B=AC/BC

=>3/BC=sin60

=>\(BC=\dfrac{3}{sin60}=2\sqrt{3}\left(cm\right)\)

=>\(AB=\dfrac{2\sqrt{3}}{2}=\sqrt{3}\left(cm\right)\)

`a,` vì Tam giác `ABC` có \(\widehat{A}=110^0\) 

`=>` Tam giác `ABC` là tam giác tù.

`b,` Cạnh đối diện của \(\widehat{A}\) là cạnh `BC`

`=>` Cạnh lớn nhất của Tam giác `ABC` là cạnh `BC`loading...
