Well flat means open so 180°
180° - 50° = 130° is the answer
If you set up a proportion, this will make sense.
Now, Cross Multiply
6x = 12.5
x = 25/12
Answer:
One example is the equation:
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.
