`Ta` `có` ; `∠N1+∠N2=180^0`
`hay` `120^0 +∠N2=180^0`
`⇒∠N2=180^0 - 120^0 = 60^0`
`Theo` `để` `bài` : `∠M2=160^0`
`⇒∠N2=∠M2=60^0`

Có : `hat{N_1} + hat{N_2}=180^o` (2 góc kề bù)
`-> hat{N_2}=180^o - hat{N_1}`
`-> hat{N_2}=180^o - 120^o`
`-> hat{N_2}=60^o`
Có : `hat{M_1}=60^o,hat{N_2}=60^o`
`-> hat{M_1}=hat{N_2}=60^o`
mà 2 góc này ở vị trí đồng vị
$→ My//Nx$ (Dấu hiệu nhận biết 2 đường thẳng song song)
Vậy $My//Nx$
