A kite with a string 80 feet long makes an angle of elevation of 40° with the ground, assuming the string is straight, how high
is the kite? Round your answer to the nearest foot. Do not include units.
1 answer:
The diagram of the kite is shown below
To find the perpendicular height of the kite from the ground, we use the trigonometry ratio for sin(x).
The reason for using the sine ratio is because we have the hypotenuse, 80 feet, and the angle, 40° and we are looking for the length of the side opposite the angle.
rounded to two decimal place
Perpendicular height of the kite from the ground is 51.42 feet

Step-by-step explanation:
The standard form of a circle is written as such:
Where (h, k) is the center of the circle, and r is the radius.
We know that the center is (-7, 0), so we can plug that into the equation like this:
The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:
So, your standard form equation is the following:
Answer:
And the best option for this case would be:
a. (17.5, 21.7)
Step-by-step explanation:
Information given
represent the sample mean
population mean
represent the population deviation
n=42 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom, given by:
Since the Confidence is 0.98 or 98%, the significance would be and
, and the critical value would be
Replacing we got:
And the best option for this case would be:
a. (17.5, 21.7)
