Answer:

-4

Step-by-step explanation:

1st Step:

Set up our equation, so we get x + 69 + 25 + 90 = 180

Remember: All sides of a triangle add to 180.

2nd Step:

Now that we've got our equation: x + 184 = 180. Subtracting 184 from 180 gives us -4, which is our answer.

Key Points To Remember:

- The angles of a triangle always add up to 180.

- The little square at the bottom of the triangle means the angle is 90.
