An outside angle is equal to the sum of the two opposite inside angles.
Set up the equation to get:
6x = (x+40) + (3x+10)
Simplify the right side:
6x = 4x + 50
Subtract 4x from both sides:
2x = 50
Divide both sides by 2:
x = 50/2
x = 25
Now you have X you can solve for each angle:
6x = 6*25 = 150
(x+40) = 25 + 40 = 65
(3x +10) = 3(25) +10 = 75 + 10 = 85

Answer:78.75
Step-by-step explanation:21 percent of 4500 945 divided my 12 which is 78.75
The equation shown above does not show the substitution property. Instead, it shows the Addition Property of Equation where 3 is added to both of its sides. This is shown below,
4x - 3 = 7
4x - 3 + 3 = 7 + 3
4x = 10
Answer:
x = -y - 4 or x = - (y + 4)
Step-by-step explanation:
p(x) = -x - 4
y = -x - 4
y + x = -x +x - 4
y + x = -4
y - y +x = -y - 4
x = - (y + 4)
