please help one blade of a fan is parallel to the floor. what degree of rotation of the fan puts the blade at the top of the fan
90 degrees
A triangular prism has a surface area of 550 square feet, a length of 15 feet, a height of 10 feet, and a side of 5 feet. Find the width of the triangular prism.
To find the degree of rotation that puts the blade at the top of the fan, we need to consider the number of blades on the fan. Let's assume there are four blades for this explanation.
Since one blade is parallel to the floor, we can picture it pointing directly upwards. The goal is to rotate the fan in a way that the current blade reaches the topmost position (also pointing directly upwards).
For a four-blade fan, we need to determine what fraction of the full rotation brings the blade from the starting position to the top position. Since one full rotation covers 360 degrees, we need to find what fraction of 360 degrees represents the rotation required to reach the top position.
Since there are four blades, and each blade is separated by 90 degrees (360 degrees divided by 4), we can conclude that a quarter of a full rotation (90 degrees) is needed to bring the blade to the top position.
Therefore, to put the blade at the top of the fan, you would need to rotate the fan by 90 degrees.
