Answer:
The correct option is 1.
Step-by-step explanation:
Inconsistent system: If the given system has no solutions, then it is an inconsistent system.
Consistent and independent system: If the given system has only one solutions, then it is an consistent and independent system.
Consistent and dependent system: If the given system has many solutions, then it is an consistent and dependent system.
The given equations are
.... (1)
..... (2)
Add both equations.



Substitute this value in equation (1).



The system of equations has only one solution, i.e.,(3,5).
Therefore the given system is consistent and independent. Option 1 is correct.
Step-by-step explanation:
In a straight line theres 180 degrees and where x is you can tell its an X lines the opposites will be the same.
First you need to work out the triangles 180-122=58 and a triangle is 180 degrees so
58+40=98 180-98=82°
now working out the other triangle.
180-82=98, 43+98=141
180-141=39
and because the opposites will end up the same x=39°
