Answer:
The additive property of equality.
Step-by-step explanation:
36 is added to both sides of the equation.
hope this helps
andddd yeaaaaaaa hope !!!!!!!
Exterior angle c = the sun of the two opposite interior angles a and b.
10x -23 = 5x -17 + 7x -26
Combine the right side:
10x -23 = 12x -43
Add 43 to both sides:
10x +20 = 12x
Subtract 10x from both sides:
20 = 2x
Divide both sides by 2
X = 10
Now you have x replace it in the equation for A:
A = 5x -27 = 5(10) -27 = 50-27 = 23
Angle A = 23 degrees.
Answer:
It's 540.
Step-by-step explanation:
