obviously not
your suppose to use Pythagorean Theorem
(a2+b2=c2
(a2+b2=c2
In the diagram, a building casts a 35-ft shadow and a flagpole casts an 8-ft shadow. If the flagpole is 18 ft tall, how tall is the building? Round to the nearest tenth.
The angle of depression from the top of the tree to the tip of the shadow is 25°. Find the height of the tree to the nearest tenth.
