Answer:

Here, we use the law of alternate interior angles. <3 and <6 are are alternate interior angles, meaning they have the same measure. We can solve x by using this equation:

3x-2=34

Add 2 to both sides

3x-2+2=34+2

3x=36

Divide both sides by 3

3x/3=36/3

x=12

2. Here, we use the law of consecutive interior angles. <4 and <6 are consecutive interior angles, meaning that the sum of their measures is equal to 180 degrees. We can solve x by using this equation:

-2x+20+6x+20=180

4x+40=180

Subtract both sides by 40

4x+40-40=180-40

4x=140

Divide both sides by 4

4x/4=140/4

x=35

3. Here, we use the law of alternate exterior angles. <7 and <2 are alternate exterior angles, meaning that their measures are the same. We can solve x by using this equation:

4x+3=x+15

Subtract both sides by 3

4x+3-3=x+15-3

4x=x+12

Subtract both sides by x

4x-x=x+12-x

3x=12

Divide both sides by 3

3x/3=12/3

x=4

4. Here, we use the law of alternate interior angles (again). <4 and <5 are alternate interior angles, meaning that they have the same measure. We can solve x by using this equation:

5x-3=3x+17

Add both sides by 3

5x-3+3=3x+17+3

5x=3x+20

Subtract both sides by 3x

5x-3x=3x+20-3x

2x=20

Divide both sides by 2

2x/2=20/2

x=10

5. Here, we use the law of consecutive interior angles (again). <3 and <5 are consecutive interior angles, meaning that the sum of their measures is equal to 180 degrees. We can solve x by using this equation:

5x-6+19=180

5x+13=180

Subtract both sides by 13

5x+13-13=180-13

5x=167

Divide both sides by 5

5x/5=167/5

x=33.4

I hope this helps!

Answer:

See below

Explanation:

1. Here, we use the law of alternate interior angles. <3 and <6 are are alternate interior angles, meaning they have the same measure. We can solve x by using this equation:

3x-2=34

Add 2 to both sides

3x-2+2=34+2

3x=36

Divide both sides by 3

3x/3=36/3

x=12

2. Here, we use the law of consecutive interior angles. <4 and <6 are consecutive interior angles, meaning that the sum of their measures is equal to 180 degrees. We can solve x by using this equation:

-2x+20+6x+20=180

4x+40=180

Subtract both sides by 40

4x+40-40=180-40

4x=140

Divide both sides by 4

4x/4=140/4

x=35

3. Here, we use the law of alternate exterior angles. <7 and <2 are alternate exterior angles, meaning that their measures are the same. We can solve x by using this equation:

4x+3=x+15

Subtract both sides by 3

4x+3-3=x+15-3

4x=x+12

Subtract both sides by x

4x-x=x+12-x

3x=12

Divide both sides by 3

3x/3=12/3

x=4

4. Here, we use the law of alternate interior angles (again). <4 and <5 are alternate interior angles, meaning that they have the same measure. We can solve x by using this equation:

5x-3=3x+17

Add both sides by 3

5x-3+3=3x+17+3

5x=3x+20

Subtract both sides by 3x

5x-3x=3x+20-3x

2x=20

Divide both sides by 2

2x/2=20/2

x=10

5. Here, we use the law of consecutive interior angles (again). <3 and <5 are consecutive interior angles, meaning that the sum of their measures is equal to 180 degrees. We can solve x by using this equation:

5x-6+19=180

5x+13-13=180-13

5x=167

5x/5=167/5

x=33.4
