The surface area of this is letter B.
Answer:
- Railway lines are example of parallel lines
- The floor and the walls of a room are example of perpendicular lines
- Two roads crossing at a signal can be termed as example of intersecting lines
Step-by-step explanation:
The lines can be related in following three ways
- Lines can be parallel
- Lines can be perpendicular
- Lines can be intersecting at an angle other than 90.
Now three real life examples of above three scenarios are described below:
- Railway lines are example of parallel lines
- The floor and the walls of a room are example of perpendicular lines
- Two roads crossing at a signal can be termed as example of intersecting lines
The one with the U shape going up, and the red line is tilting to the left that last picture
Answer:
Step-by-step explanation:
1. 2x + y
2. 48 + 60 = 108
3. 840 - 210 = 630
