Which angles are congruent?

a. a 30° angle and a 60° angle

b. a 60° angle and a 60° angle

c. a 60° angle and an 120° angle

d. none of the above

B.

Step-by-step explanation:

My answer is B because congruent angle have the same angle either in degree or in radians. So a 60° angle and a 60° angle are the same.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
