## Answers ( )

Answer:Step-by-step explanation:3x + 120 = 360 {angle sum prop}

3x = 360 – 120 =240

## x=80 °

## hope it helps

Answer:one angle –:120

opposite angle —:120°

now,

corresponding angle –:180-120–:60°

opposite angle–:60°

then ,

1st angle –:120°

2. —:60°

3. —:120°

4. —–:60°

then,

proved

130+60+120+60–:360°
