The sun is at an angle of elevation of 58°. A tree casts a shadow 20 meters long on the ground. How tall is the tree?
Here, the height of the tree is labeled " t " .
Since the tree makes a 90º angle with the ground, we can say...
tan 58º = t / 20 Multiply both sides of the equation by 20 .
20 tan 58º = t Put this into a calculator to get that...
32.007 m ≈ t
