A typical windmill has three blades. We can envision these blades in a circle, which a circle = 360 degrees. We want to divide up the angles of the blades so they are even or makes up 360 degrees. We have three blades so we have 3 angles to divide by 360 degrees. So, 360 / 3 = 120 degrees. Now that we know the angle of the blades, we can use the Law of Cos to solve the distance between the blade tip.
Law of Cos
We know
a = 20
b = 20
A = Angle = 120
We need to solve for c
Take the square root of each side of the =
Input the values we know into the formula and solve for c:
We now have our answer, which is 34.64 and that is C.
Answer:
83
Step-by-step explanation:
You are trying to find the score that gives you a specific mean. A mean is calculated by dividing the sum of the data by the amount of data. Set up in this order, with x as the fourth score, to find the answer.
The fourth test score must be an 83.
