X= 100°
180° - 57° = 123
x + 23°= 123°
x = 100°
80,000,000 + 9,000,000 + 100,00 + 70,000 +300 + 20 + 6
Just divide both sides by 2 because you want to do the opposite operation, to isolate x so if you do you get 80 so x = 80
If you multiply 3 and 3 and 3
This statement is obviously FALSE because the vertical angles are congruent, whatever is the measure of one the two angle, but the linear pair is two angles that lie next to each other and their measures add up to 180 degrees. The linear pair is also a pair of adjacent angles formed by intersecting lines.
