Step-by-step explanation:
z°=180°-25°
z°= 155°
z°=x°=155° (vertically opposite angle).
w°=25°(alternate angle).
y°=z°=155°(alternate angle).
hope this helps you.
9x-y = 45
Move 9x to the other side. Sign changes from +9x to -9x.
9x-9x-y=45-9x
-y=45-9x
Multiply both sides by -1
(-1)(-y)=y
(-1)(45)=-45
(-1)(-9x)
y=-45+9x or y=9x-45
Answer: y=-45+9x or y=9x-45
The answer is 1/24. Hope that is right
