Answer:

7 ft

Explanation:

First of all, "10 inch" would be "10 feet".

Now,

the height of the body from the frame at 45% angle would create a 45-45-90 degree triangle.

From the triangle, the body height (h) divided by
√(2) would give us the approximate height of the body from the frame.

So,


(10)/(√(2) )=7.07

So, the 10 feet body would be around 7.07 feet from the frame. Rounded to nearest inch, it would be 7 feet.
