Answer:
They are congruent, they are right angles
Step-by-step explanation:
Just in general, all vertical angles are congruent.
But in this situation, perpendicular lines will always create right angles.
Step-by-step explanation:
4x + 12° = 64° ( vertically opposite angle )
4x = 64° - 12°
4x = 52°
x = 52° / 4
x = 13°
hence the value of x is 13°
We have ax - bx = 1;
Then (a - b)x = 1;
If a - b is not 0, then x = 1 / (a-b);
