The windmill's blade measures 7 feet in length.
<h3>What is an equation?</h3>- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
To find the measure of the windmill's blade:
- We have the equation:
- At the time 't' = 0, the end of the blade is parallel to the ground and pointing to the right, indicating that it is the same height as the other end. (Ф = 0°)
- We may calculate the length of the blade by calculating the greatest height of this end at = 90°.
- We now know that the general model equation of a circular simple harmonic motion is written as follows: y = A sinωt + k
- Where A is the maximum displacement from mean to maximum position
- The angular frequency is ω.
- When eq1 and eq2 are compared:
- A = 7
- As a result, the difference in blade end height at = 0° and = 90° is 7 feet.
Therefore, the windmill's blade measures 7 feet in length.

The correct question is given below:
The equation h=7sin(pi/21t)+28 can be used to model the height, h, in feet of the end of one blade of a windmill turning on an axis above the ground as a function of time, t, in seconds. How long is the blade? Assume that the blade is pointing to the right, parallel to the ground, at t = 0, and that the windmill turns counterclockwise at a constant rate. 7 feet 14 feet 21 feet 28 feet
now, the angle of θ, can only have a "y" value that is positive on, well, y is positive at 1st and 2nd quadrants
and "x" is positive only in 1st and 4th quadrants
now, that angle θ, can only have those two fellows, "y" and "x" to be positive, only in the 1st quadrant, and also both to be negative on the 3rd quadrant.
and that those two fellows, can also be both negative in the 3rd quadrant
3/1 = 3, and -3/-1 = 3
so, the solutions can only be "3", when both "y" and "x" are the same sign, and that only occurs on the 1st and 3rd quadrants
