Final answer:
To find the value of x in the given regular pentagon, set the expressions AB and CD equal to each other and solve for x.
Step-by-step explanation:
To find the value of x, we need to set the expressions AB and CD equal to each other:
14x - 34 = 7x + 8
Subtract 7x from both sides, then add 34 to both sides:
7x = 42
Divide both sides by 7:
x = 6
Therefore, the value of x is 6.
