Not sure how to solve. Julia uses the shadow of a flagpole to estimate its height. She stands so that the tip of her shadow coin
cides with the tip of the flagpole’s shadow, as shown. Julia is 5 feet tall. The distance from the flagpole to Julia is 28 feet, and the distance from the tip of the shadows to Julia is 7 feet. Calculate the height of the flagpole. a. 13 feet b. 980 feet c. 39 feet d. 25 feet
You are going to have to compare the height and shadow of Julia to the height and shadow of the flagpole. Julia is 5 feet tall with a shadow of 7 feet. The flagpole is "x" feet tall with a shadow of 35 feet (to get 35, I added 28 feet and 7 feet.) So, you do 5/7 = x/35 You cross multiply and get 175 = 7x Then, divide by 7 and you get 25. 25 feet is the height of the flagpole, so it would be option "D".
