Answer:
156°
Step-by-step explanation:
Angle V + Angle T + Angle U = 180°
( angle sum property of triangle)
U + V + T = 180°
103° + 53° + U = 180°
156° + U = 180°
U = 180° - 156°
U = 24°
Now, angle VUT + angle VUX = 180°
(linear pair)
24° + ? = 180°
? = 180° - 24°
VUX = 156°
Hence, the exterior angle is 156°.
