Answer:
idk just google it :)
Step-by-step explanation:
1. google it
Not sure what the question is asking, but what you listed is true. Percentage is out of 100 and the denominator would always be 100.
Answer:
x = 12
A = 83
B = 38
c = 59
Step-by-step explanation:
You can use the sin function to solve this.
Think of a triangle with the conveyor being the longest side (hypotenuse). The height (the vertical side) is H=17m. The angle of elevation is a=36.2. We are looking for length of the hypotenuse, L.
The sin is the ratio of height to hypotenuse: sin(36.2) = H/L = 17/L
Now solve for L:
L = 17/sin(36.2) = 17m/0.59 = 28.78m
The conveyor needs to be approx. 28.8m long to get close to the max. efficient angle.
