Sheila is climbing on a ladder that is attached against the side of a jungle gym wall. she is 5 feet off the ground and 3 feet from the base of the ladder, which is 15 feet from the wall. how high up the wall is the top of the ladder?

The ladder is leaning against the wall, the information you're given, being that she's 5 feet up and 3 feet from the wall shows that every 3 feet she moves on the ladder, she moves up 5 feet, the ladder is 15 feet away from the wall so 15/3 is 5 multiply that by 5 to get the total length of the ladder, which is 25. Then use Pythagorean theorem (A^2 + B^2 = C^2)
15 would be the A or B value because it's the distance from the wall, the C value, or the hypotenuse would be 25 because it's the total length of the ladder, replace the variables so you get A^2 + 15^2 =25^2 then square the integers, and get A^2 + 225 = 625, subtract 225 from each side and you're left with A^2 = 400, take the square root of each side (√A^2 = √400) and you're left with your answer of A=20
