Answer:50 degrees
Step-by-step explanation: The 105degrees angle forms a supplementary angle with the missing degrees in the triangle
so the missing value which is not requested is 180degrees-105 degrees=75 degrees
No we have two angles inside the triangle. We can now work out the missing angle for x
We know that a triangle adds up to 180 degrees
So x=180-55-75=50 degrees as the answer
