To solve for x, put all of the angle measurements on one side of an equation and set it equal to 360, because the sum of any exterior angles is 360 degrees. hope this helped!
I am pretty sure it is 180 degrees
Ok so find greatert common factor
ab+ac=a(b+c)
15x=3*5*x
9=3*3
gcf=3
15x-9=
3(5x)+3(-3)=
3(5x-3)
possible dimentions is 3 unit and 5x-3 units
Answer: i think 0.8.
