5. x+4x+5=180 —-> 5x+5=180—> 5x=175—>x=35 (same side interior/supplementary)
6. 6x=144–> x=24. (congruent segments, are bisected)
7. x+27=2x-1 —-> x=28 (corresponding angles are congruent)
8. 2x-17+63=180 —-> 2x=134 —-> x=67
9. 9x-28=7x+12 —> 2x=40 —> x=20 (corresponding sides are congruent)
10. 5x+7= 82 —-> 5x=75 —-> x=15
11. 7x-8=41 —-> 7x=49 —> x=7
12. 6x-12=114 —> 6x= 126 —-> x= 21

Hope that helps!

Answer:

5) 35

6) 24

7) 28

8) 67

9) 20

10) 11

11) 7

12) 21

Explanation:

Looks like you get most of the rules involved so I'll just write the steps

5) x+4x+5 = 180

5x + 5 = 180

5x = 175

x = 35

6) 6x = 144

x = 24

7) x+27 = 2x-1

27 = x-1

28 = x

8) 63+2x-17 = 180

2x + 46 = 180

2x = 134

x = 67

9) 9x-28 = 7x +12

2x = 40

x = 20

10) 5x+7 = 62

5x=55

x=11

11) 41=7x-8]49=7x

7=x

12) 114=6x-12

126=6x

21 = x

If you wanna check it just plug in the values

That's about it
