Answer:

The distance between the centers of the gears is 27.4 inches

Explanation:

see the attached figure with letters to better understand the problem

In the right triangle ABC

Applying the Pythagorean Theorem


AC^2=AB^2+BC^2

we have


BC=CE-EB=9.3-2.4=6.9\ in


AB=DE=26.5\ in

substitute


AC^2=26.5^2+6.9^2


AC^2=749.86\\AC=27.4\ in

therefore

The distance between the centers of the gears is 27.4 inches
