Angle x° and angle
154° are supplementary angles, meaning that they equal 180° when added.
i don't know how to type the answer out but it's on the work i just did ⬆️
No it does not change it is a imaginary like used to move a figure. Nor does it move when it is rotated
Ok ok I know you hate links but this is the only way to show you the answer.

The entire answer is explained in there
Simplify both sides of the equation
-4.8=1.2s+2s+4
Combine like terms
-4.8=(1.2s+2s)+(4)
-4.8=3.2s+4
Flip the equation
3.2s+4=-4.8
Subtract both sides by 4
3.2s+4-4=-4.8-4
3.2s=-8.8
Divide both sides by 3.2
3.2s/3.2= -8.8/3.2
S=-2.75 will be the answer hope it helps
