The absolute value makes it 9
Answer:
55°
Step-by-step explanation:
y+x=180°
25°+30°+x=180°
25°+30°=y
y=55°

The perimeter would be rational due to both the width and length being rational numbers. A rational number is a number that can be written as a fraction such as 8 it can be written as 8/1, but a irrational would be a decimal number which in this case there would be none because both length and width is rational number. For example, Lets say the width is 8 and the length is 10. once both are written into fraction form such as 8/1 and 10/1 we add them to get a perimeter of 18.
