Answer:
x = 100°
Step-by-step explanation:
in the given figure
(x + 23°) + 57° = 180°
(they form linear pair)
- x + 23° + 57° = 180°
- x + 80° = 180°
- x = 180° - 80°
- x = 100°
The tens column is the one directly to the right of the decimal, so you need to get rid of the seven. Since the 7 is closer to ten than it is to zero (it's bigger than 5), you will round up. When you round up, you add 1 to the number on the left, the 9. So it will become 10, or 1.0
What are the options? It asks "Which of the following equations" but they aren't available to choose from.
