Question

Answer 1

yHK + xKH = 180*

=> xKH = 180* - 115* = 65*

Answer 2

\(MH//NK=>\angle\left(yHK\right)+\angle\left(xKH\right)=180^o=>\angle\left(xKH\right)=180-115=65^o\)

Answer 3

Answer 4

Ta có: MH//NK(gt)

nên \(\widehat{yHK}+\widehat{xKH}=180^0\)(hai góc trong cùng phía)

hay \(\widehat{xKH}=35^0\)

Vậy: \(\widehat{xKH}=35^0\)
