A fence 10 feet tall runs parallel to a tall building at a distance of 5 ft from the building as shown in the diagram. LADDER 10 ft Q 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 0. (Hint: split the ladder into 2 parts.) Type theta for 0. [B] Now, find the derivative, L'(0). Type theta for 0. [(] Once you find the value of @ that makes _ '(0) - 0, substitute that into your original function to find the length of the shortest ladder. (Give your answer accurate to 5 decimal places.) L(8 min ) = feet Submit
