Answer:
you could stand at 5.0 ft and still be completely in the shadow of the tree
Step-by-step explanation:
From the diagram attached below;
We consider;
to be the height of the tree and
to be the height of how tall you could be and still be completely in the shadow of the tree.
∠D = ∠B = 90°
Also;
ΔEAD = ΔBAC (similar triangles)
Therefore, their sides will also be proportional
i.e
By cross multiply
225x = 45 × 25
x = 5.0 ft
Therefore, you could stand at 5.0 ft and still be completely in the shadow of the tree
