Answer:
90
Step-by-step explanation:
x=95 degrees
All of the angles in a triangle add up to 180, so 45+50+(180-x)=180.
Open the parenthesis, and you get 45+50+180-x=180.
Then subtract 180 from both sides, so 45+50-x=0.
Simplify that to 95-x=0, and add x to both sides.
x=95
Also, you can use exterior angles theorem, which states that 45+50=x.
That's the shorter way.
