Question

Help please I don't know what to do on this and it is urgent I need this in 20min.

Answer 1

Question 1

`\angle 1` and
`\angle 2` are supplementary.

`3x+20+x=180 \\ \\ 4x+20=180 \\ \\ 4x=160 \\ \\ x=40`

`\angle 1` and
`\angle 4` are vertical angles. Thus,
`m\angle 4=3(40)+20=140^(\circ)`.

Question 4

`105+3x=180 \\ \\ 3x=75 \\ \\ x=25`
