What is angle A’s equation
Answer:
18 rungs
Step-by-step explanation:
Let x = number of rungs
x/2 = middle
Climbed 3
x/2 +3
Down 5
x/2 +3 -5
Climbed 9
x/2 +3 -5+9
Then climbed 2 more
x/2 +3 -5+9 +2
Now is at the top
x/2 +3 -5+9 +2 =x
Combine like terms
x/2 +9 = x
Subtract x/2 from each side
x/2+9-x/2 = x - x/2
9 = x/2
Multiply each side by 2
18 =x
