A 15 foot tall tree is next to a slide tree is casting a shadow of 20 feet and the slide is casting a shadow that is 16 feet how tall is the slide

Ok ratio and proportion

realheight:shadow=15:20

slide shadow=16

therefor find realheightslide

15:20=realheightslide:16

simplify

3:4=realheight:16

fractionfy

3/4=realheight/16

multiply both sides by 16

48/4=realheight

12=realheight

aswer is 12 feet
