The base of a ladder leaning against a house is 30ft from the wall. if the ladder reaches 40ft high on the wall , how long is the ladder?

• Math -

Since this forms a right-angle triangle, we can use the Pythagorean Theorem.

a^2 + b^2 = c^2

30^2 + 40^2 = c^2

900 + 1600 = c^2

2500 = c^2

50 = c
