Answer:
m angle A = x = 30 degrees
Step-by-step explanation:
Vertical angles are equal.
So 3x - 60 = x
2x = 60
x = 30
Answer:
Vertical angles are always equal.
So you can set the equation up like this:
5x + 10 = 7x - 12
Subtract 5x from both sides. Then Add 12 to both sides.
22 = 2x
Divide both sides by 2.
11 = x
