Answer:
x = 10
Explanation:
Since the ray AE is an angle bisector, it means that it cuts the angle 50 / 50, or perfectly in half.
This means that angle BAE and angle EAC are actually congruent
∠BAE = ∠EAC
Get rid of x on one side. Since you are solving for x, use the more simple x
This becomes this ⇅
Subtract 10 from both sides
20 = 2x
20 divided by two
2x divided by two
x = 10
