If ∠AOC and ∠BOD are vertical angles, then they are congruent.
Thus,
21° = (2x + 39)°
Subtracting 39 from both sides, we get:
-18° = 2x
Dividing by 2, we get:
x = -9
Therefore, the value of x is -9.
Thus,
21° = (2x + 39)°
Subtracting 39 from both sides, we get:
-18° = 2x
Dividing by 2, we get:
x = -9
Therefore, the value of x is -9.
