The tangent of 42 degrees is approximately 0.9004. To calculate this, you can use a scientific calculator or a trigonometric table. The tangent function in trigonometry is defined as the ratio of the length of the side opposite to the angle to the length of the side adjacent to the angle in a right triangle.
The angle of repose for dry shelled corn is 23 degrees or a tangent of .42

Tangent = 0.5
The tangent of 0.47 radians is about 0.508. The tangent of 0.47 degrees is about 0.00820.
The inverse tangent is 0.83448691252602 degrees.
Tangent of theta = Y/X, or opposite the angle/the adjacent of angle. So; Tangent of 42 degrees = height/80' 80' tan 42 = height = 72 feet ( you might want to subtract that 4.5 foot eye height )
31 degrees
