Adjacent angles are angles with a common side and vertex, linear pairs are adjacent angles that are supplementary, and vertical angles are angles made by the same two lines but on opposite sides.
For the first one, 5 and 6 clearly do not share a side but they are made up by the same 2 lines and are opposite of each other, making them vertical.
For the next one, since the angles only share 1 line (and not a side) they can't be any of the above.
Answer:
Answer: 60%
Step-by-step explanation:
<u>No solution</u>: because the absolute value is positive and can't equal a negative
|x| = -1
<u>One solution: </u>because zero only has one sign
|x| = 0 ⇒ x = 0
<u>Two solutions:</u> absolute value is positive whether x is positive or negative.
|x| = 2 ⇒ x = 2 or x = -2
