Step-by-step explanation:

We can solve this problem by using proportions.  Take the size of the item over the shadow.

40 ft  pole             x ft tree

=

12 ft   shadow        8.4 ft shadow    

Using cross products

40 * 8.4 = 12 * x

336 = 12x

Divide each side by 12

336/12 = 12x/12

28 ft = x
