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.
1 answer:
Answer:
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
