To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that

we can subtract twenty from each side


now we can subtract like terms

so we can get the final answer as
Total = 21 feet
if each is 3 feet
21/3 = 7
Therefore, there are 7 sections
Answer: 3 - x
Step-by-step explanation: With
Subtraction be careful. 3 - x is not the same as x - 3. You have to keep the values given in order.
