Yes, they can add up to 180 degrees. Say one angle is 65 degrees, and the other one is 115 degrees. That would equal to 180 degrees.
Hope this helps.
If the length is 7/6 the width w then the perimeter is w + (7/6)w + w + (7/6w)
= 2((7/6)w + w) = 2w + (14/6)w = (26/6)w = (13/3)w.
So the answer is the last one.
Answer:
-10b - 7
Step-by-step explanation:
-11b - 4
- (-b + 3)
-----------------
-10b - 7
131.818182% and can round to 131.82
1) (solve for Y 1st)
-4y=16
y=-4
slope=0 y-inter= -4
2)(solve for X 1st)
6x=12
x=2
slope=undefined y-inter= none
