What is the value of x?

x=95 degrees

Step-by-step explanation:

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.
