A=88 because it is and i like to have points so thank u lol
what is suppoesed to be solved
the letter b?
These two angles are equivalent because they're corresponding angles created by two parallel lines.
Since they're equivalent, we can set them equal to each other.
23x - 5 = 21x + 5
Now solve for x
23x - 5 = 21x + 5
Add 5 to both sides
23x = 21x + 10
Subtract 21x from both sides
2x = 10
Divide both sides by 2
x = 5
Now, plug in 5 as "x" in one of the equations
Angle 1 = (23*5) - 5
= 115 - 5
= 110 degrees
Since they're equivalent, Angle 2 should also be 110 degrees, but let's check in case.
Angle 2 = (21*5) + 5
= 105 + 5
= 110 degrees
