Answer:
Angles 1 & 2 are vertical angles, and angles 3 & 4 are adjacent angles.
Step-by-step explanation:
Vertical angles are angles across from each other. Adjacent angles are always beside each other.
It's not a linear pair because a linear pair is adjacent angles that add up to 180°, which is not true for your 2 angles in the picture. Hope this helps!!!

Answer:
2650
Step-by-step explanation:
Given: 2648
Two significant figures means we need to round off to the nearest tens place.
In 2648, the tens place is 4
To round off the tens place, we need to look for the next digit that is right to tens place, which is 8
8 is greater than 5, so we need to add 1 with tens place (4 +1 = 5)
Therefore, it is 2650
Hope this will helpful.
Thank you.
