A large totem pole in the state of Washington is 100 ft tall. At a particular time of day, the totem pole casts a 249-ft-long shadow. Find the measure of angleA to the nearest degree.

anonymous · Answer

Assuming 
1. the large totem pole is straight, perpendicular to the ground and, 
2. the ground in Washington adjacent to the large totem pole is level and, 
3. angle A is viewed from the ground, then
Angle A = the tangent of the opposite length / adjacent length
Angle A = the tangent of 100 ft / 249 ft
Angle A = tan(100/249)
