Answer:
10 feet higher.
Pine tree measure = 40 feet in height
Explanation:
This is because the Flag pole of 50 feet in measure cast a shadow of 15feet and nearby to the pine tree (meaning same dilation would occur for such shadow) where pine tree shadow is given measure of 12 feet.
Flag Pole multiplier = 50 / 15 = 3 1/3
Pine Tree true measure = 12 x 3 1/3 = 40 feet in height
