Answer: x = 23
Explanation:
The sum of interior angles in a triangles is equal to 180°, therefore:
(2x - 1) + 110 + 25 = 180
1. Get rid of parentheses.
2x - 1 + 110 + 25 = 180
2. Add the number up in the left side.
2x + 134 = 180
3. Subtract 134 from both sides.
2x = 46
4. Divide by 2 from both sides.
x = 23
