an observer from the ground looks up to the top of a building with an angle of elevation of 24 degrees. If he is standing 400 feet away from the building, how tall is the building? Round to nearest foot.
Just, tan function, \(\boxed{178}\) feet.
You would use the "tan function" to find the height of the building:
Tan(24) = Height / 400
0.445229 = Height / 400
Height = 400 x 0.445229 =~178 feet - Height of the building.
