plz help will mark as brainliest

Answer:
X = 36 Plz mark brainliest :)
Step-by-step explanation:
This is quite easy actually. If you look on the right you see that the exterior angle next to x is 144 degrees. We know that a straight line is 180 degrees so to find x we can do 180 = x + 144.
Answer:
∠ACB = 36°
∠ABC = 60°
Step-by-step explanation:
∠ACB = 180 - 144 (Linear Pair)
therefore, x = 36°
∠ABC = x + 24°
∠ABC = 36 + 24
∠ABC = 60°
