In the diagram, a building casts a 35-ft shadow and a flagpole casts a 10-ft shadow. If the flagpole is 22 ft tall, how tall is the building? Round to the nearest tenth. 77.0 ft 15.9 ft 37.0 ft 53.0 ft

do you have the diagram? can you show it to us? :)

OpenStudy (anonymous):

i dont know how to do that

OpenStudy (anonymous):

use the draw button or take a picture of it and attached it here

This is a proportion problem. Set 35/x=10/22. Cross multiply and divide by the number in front of the variable

OpenStudy (anonymous):

(35*22)/10

ok, if you'll look at the diagram, we now that they are similar triangles so let's say x is the height of the building, \(\Large \frac{x}{35}=\frac{22}{10}\) solving for x , you'll have to cross multiply it, so \(\Large x=\frac{(22)(35)}{10}\), solve it then tell us what you got :)
