Answer:
X = 66
Step-by-step explanation:
A straight line is equal to 180 degrees so if you have one side of that line you can figure out the inside angle.
Now that you have two of the angles inside the triangle add them up. All the interior angles of a triangle will add to 180. So add up 38 and 76 to get 114. Now do 180 - 114, you should get 66
so x = 66
Answer:
Step-by-step explanation:
We are told the wind turbine makes 76 revolutions in 1 minute. This means the angular speed of the object in revolutions per minute (rpm) is:
(1)
However, we have to convert this to , since this is the unit used in the International Systme of Units for angular speed.
So, we can do this knowing that:
(2)
Where:
is the value of one revolution
is the period of rotation
With this information in mind, let's make the conversion:
(3)
(4) This is the wind turbine angular speed
