Answer:
Explanation:
A silo is a tall thin structure used to store grain -- just in case you live somewhere where you wouldn't know that.
Draw a right triangle.
The vertical length = 50 feet
The horizontal length = 87 feet.
The angle of elevation is at the end of the 87 foot length to the top of the vertical length.
Tan(angle of elevation)= 50 / 87 Take the inverse tan of both sides
angle of elevation = tan-1 (50 / 87)
angle of elevation = 29.89 degrees
