Question

You are on level ground in the late afternoon. The Sun is at angle of elevation of 17 degrees. A tree casts a 206-foot long shadow feet. What is the height of the tree in the nearest foot

​

Answer 1

• AB is the tree

`\\ \sf\longmapsto tanC=(AB)/(BC)`

`\\ \sf\longmapsto tan17=(AB)/(206)`

`\\ \sf\longmapsto AB=0.3(206)`

`\\ \sf\longmapsto AB=61.8ft`
