<span>We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
</span>On September 22, the sun’s rays form a 90° angle at noon at the equator.
Formula for calculating noon sun angle is:
Noon_sun_angle = 90° - Zenith angle
We have complementary angles so we need to substract zenith angle from 90°.
The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.
New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°
Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°
The total will be $19.72 with 20% so she will get back $30.28
I think the orange one is correct.
The x and y coordinates of point S are increased by three to get to the midpoint.
(2,1) ----> (5,4)
To get to point t increase the coordinates by three again.
(5,4) -----> (8,7)
answer: (8,7)
2 feet = 24 inches
24 inches divided by 1 inch = 24
Answer is 24 pillows.
