Which of the following statements best describes vertical angles? a. vertical angles are adjacent angles. b. vertical angles are complementary angles. c. vertical angles are nonadjacent angles. d. vertical angles are supplementary angles.

C.  Vertical angles are nonadjacent angles.  

Step-by-step explanation:

C.  Vertical angles are nonadjacent angles.  

Vertical angles are nonadjacent angles.

Step-by-step explanation:

Definition of vertical angles : Vertical angles are a pair of non-adjacent angles formed when two lines intersect.

Definition of complementary angles : A pair of angles whose sum is 90° are said to be complementary angles.

Definition of non adjacent angles : A pair of angle is said to be non adjacent if they are not having the vertex and one side in common.

Definition of Supplementary angles :  A pair of angles whose sum is 180° are said to be Supplementary angles.

By considering the above definitions we can say that Option C is true.

Vertical angles are nonadjacent angles.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
