Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is 
x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 = (140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
Answer:
27 feet.
Step-by-step explanation:
This is quite simple. As a square has equal lenght and width we can tell that 6x6=36. So each side has a lenght of 6 feet. With only 3 sides needed for fencing, 6x3=27. Mrs. Roberts needs 27 feet of fencing.

Rule: Negate x. (-x,y)
f(x)=g(-x)
f(x) 5x+8
g(x) = -5x+8
