Use each diagram to solve for x.

1. x =

2. x =

see explanation

Step-by-step explanation:

Since the lines are parallel then

6x + 3 and 45 are alternate angles and congruent, hence

6x + 3 = 45 ( subtract 3 from both sides )

6x = 42 ( divide both sides by 6 )

x = 7

Since the lines are parallel then

7x - 1 and 5x + 19 are corresponding angles and congruent, hence

7x - 1 = 5x + 19 ( subtract 5x from both sides )

2x - 1 = 19 ( add 1 to both sides )

2x = 20 ( divide both sides by 2 )

x = 10

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

each side has a different length.
