Answer:

AB = 21

Step-by-step explanation:

BC and DE are sides of a regular pentagon, so their lengths are equal.

5x - 4 = 2x + 11

3x = 15

x = 5

All sides are congruent, so AB = BC = 5x - 4

AB = BC = 5x - 4

AB = 5(5) - 4

AB = 25 - 4

AB = 21

Solve for x (30+x)+30+9x=360
UkoKoshka [18]

Answer:

x=30

Step-by-step explanation:

(30+x)+30+9x=360

We move all terms to the left:

(30+x)+30+9x-(360)=0

We add all the numbers together, and all the variables

(x+30)+9x+30-360=0

We add all the numbers together, and all the variables

9x+(x+30)-330=0

We get rid of parentheses

9x+x+30-330=0

We add all the numbers together, and all the variables

10x-300=0

We move all terms containing x to the left, all other terms to the right

10x=300

x=300/10

x=30
