Hey there!
63 = 13 + 2P subtract 13 from both sides
50 = 2P divide both sides by 2
25 = P
So the cost of one pass = $25
Hope this helps!
Your answer is in the picture above

EA^2 = EC*CD
12^2 = 8*(x+10)
and now ED = EC+CD = 8+x+10
I suspect a typo somewhere in the murk above
The degree measure is about 59° and the length of the ladder is 10√34 in or about 59.3in
