the sum of supplementary angles is 180 degree
therefore
x +2x = 180°
3x = 180
X = 180/3 = 60°
the value of X is 60°
The equation of the vertical line that satisfies the condition is x=0.
The solution to the equation includes both the positive and negative portions of the solution. x = 12, -12
Answer:
x = 0 or x = 3
Step-by-step explanation:
if f(x) = g(x) then – x2 + 4x + 1 = x + 1
add the like terms
-x^2 +3x = 0
-x (x-3) = 0 then x is either 0 or 3
