Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower.
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let

be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find

:


We can conclude that the tower is 137.27 meters tall.
