Question

I need help please!!!

Answer 1

1. yes (the given angles are co-interior {130+50=180} )
2. yes( corresponding angles are equal)
3. .....
4. yes (exterior alternate angles are equal)
5. yes ( vertically opposite angles are equal)

7) 3x=45( corresponding angles formed on parallel lines)

x=45/3

x=15

8)120=2x+10(corresponding angles formed on parallel lines)

or,120-10=2x

or,110/2=x

or,x=55
