Stephanie casts a shadow of 1.2m and she is 1.8m tall. A wind turbine casts a shadow of 10m at the same time that Stephanie measured her shadow. Draw a diagram of this situation and then calculate how tall the wind turbine is.

Ms. Sue,
Use a proportion to solve this problem.
1.2 / 1.8 = 10/x
Cross multiply and solve for x.
