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

$\\ \sf\longmapsto tanC=\dfrac{AB}{BC}$

$\\ \sf\longmapsto tan17=\dfrac{AB}{206}$

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

$\\ \sf\longmapsto AB=61.8ft$
