Please help I’m confused

x=18

Step-by-step explanation:

those angles are vertically opposite so 3x+20=5x-16

means 74=74 which is true

Step-by-step explanation:

since vertical angles are congruent we can use the following formula to find x

3x+20=5x-16

5x-16=3x+20

5x-3x=20+16

2x=36

x=18

Thus, the answer is 18 degrees

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

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
