On a sunny afternoon, the stratosphere tower casts a shadow that is 140 meters long. at the same time, a nearby flagpole that is 10 meters tall casts a shadow that is 4 meters long. write and solve a proportion to find the height of the stratosphere tower.

x m tall                     10 m tall

         =

140 m shadow           4 m shadow

The height of the Stratosphere Tower is 350 m

Step-by-step explanation:

We can use proportions to solve this problem.  Put the height of the object over the length of the shadow.

x m tall                     10 m tall

         =

140 m shadow           4 m shadow

Using cross products

x*4 = 10 * 140

4x =1400

Divide by 4

4x/4 = 1400/4

x =350

The height of the Stratosphere Tower is 350 m
