Show Intro/Instructions A fence 4 feet tall runs parallel to a tall building at a distance of 2 ft from the building as shown in the diagram LADDER 4 ft We wish to find the length of the shortest ladder that will reach from the ground over the fence to the wall of the building. [A] First, find a formula for the length of the ladder in terms of θ. Hint: split the ladder into 2 parts.) | Type theta for θ. ã(0) = Preview [B] Now, find the derivative, L'(0). Type theta for θ ã,(0) = 1 Preview [C] Once you find the value of θ that makes L'(0) = 0, substitute that into your original function to find the length of the shortest ladder. (Give your answer accurate to 5 decimal places.) feet Points possible: 1 Licer
