Bạn chỉ cần vận dụng cái tổng 3 góc của 1 tam giác là dc mà

Còn cái x thì là gộp thành nhân 2x hoặc 3x 

Sau đó lấy 180 : cho là ra

18 tháng 10 2021

Hình 1 :

Vì tông 3 góc trong 1 tam giác luôn bằng 180o nên \(\widehat{B}+\widehat{C}+x=180^o\)

\(\Rightarrow55^o+35^o+x=180^o\)\(\Rightarrow90^o+x=180^o\Rightarrow x=180^o-90^o=90^o\)

Tương tự với hình 2 , ta tính được :

Hình 2 : \(x=110^o\)

Hình 3 : 

Vì tổng 3 góc trong 1 tam giác luôn bằng 180o nên : \(\widehat{N}+x+x=180^o\)

\(\Rightarrow50^o+2x=180^o\Rightarrow2x=180^o-50^o=130^o\Rightarrow x=65^o\)

Hình 5 : 

Vì AB ⊥ AC => \(\widehat{B}=90^o\)mà tổng 3 góc trong 1 tam giác luôn bằng 180o nên :

\(\widehat{A}+60^o+x=180^o\)\(\Rightarrow60^o+x=120^o\)\(\Rightarrow x=60^o\)

Hình 6 : 

Vì IH ⊥ HG => \(\widehat{H}=90^o\)mà tổng 3 góc trong 1 tam giác luôn bằng 180o nên :

\(90^o+x+x=180^o\Rightarrow2x=90^o\Rightarrow x=45^o\)

Hình 7 : 

Vì KJ ⊥ JL => \(\widehat{J}=90^o\)mà tổng 3 góc trong 1 tam giác luôn bằng 180o nên :

\(90^o+2x+x=180^o\)\(\Rightarrow3x=90^o\Rightarrow x=30^o\)
