Tony has a vegetable garden that is 15 feet wide and 20 feet long. he planted corn in an area that is 5 feet wide and 15 feet long. what area of the the garden is not planted in corn?

angle 5 and angle 6 are adjacent angles, all adjacent means is directly next to each other, another example would be 6 and 1; 1 and 2; 2 and 3, etc

and example of vertical angles would be 6 and 3, they basically form an x, another example is 5 and 2, 1 and 4, etc

an examples of angles that would qualify as neither would be 1 and 3, they are not next to one another, thus they are not adjacent, and they do not form an x so they are not vertical, another example would be 5 and 3
