Answer:

The distance between the centers of the gears is 27.4 inches

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In the right triangle ABC

Applying the Pythagorean Theorem

[tex]AC^2=AB^2+BC^2[/tex]

we have

[tex]BC=CE-EB=9.3-2.4=6.9\ in[/tex]

[tex]AB=DE=26.5\ in[/tex]

substitute

[tex]AC^2=26.5^2+6.9^2[/tex]

[tex]AC^2=749.86\\AC=27.4\ in[/tex]

therefore

The distance between the centers of the gears is 27.4 inches
