33 degrees perpendicular to the horizon
what is the formula for a vertical angle
The sign for a vertical angle is......(I don't know actually >.
Eratosthenes' method requires that one know or determine the vertical angle of the sun above the horizon or from the zenith (a point directly overhead) at solar noon at two locations along the same line of longitude. The distance between the two locations must also be known.
Yes.
Vertical angles can be acute, right (if the intersecting lines forming them are perpendicular) or obtuse.
Local noon.
The steepest sun angle reached in Houston, TX is on June 21 during solar noon. That angle is 83.7 degrees (almost straight up). Vertical objects will have the shortest shadows on June 21. To find the solar noon sun angle on the summer/winter solstice and spring/fall equinox for your location, simply find your latitude and subtract it from 90. Then add 23.45. Houston's latitude is 29.75 degrees north of the equator. So... 90-29.75=60.25 60.25+23.45=83.7 degree sun angle
An angle of 43 degrees cannot be a vertical angle. A vertical angle, by definition, is 90 degrees
what is the formula for a vertical angle
it decreases steadily
It varies with the time of the year ; but it occurs at solar noon within 23 degrees of the equator (at the equator at the two equinoxes).
No. Or at least, I think not.
It can be almost any measure but the important thing to remember is that vertical angles are congruent, so any angle that is vertical to another has the same measurement as the angle it is vertical to.
The same as local apparent noon. When the sun is the highest in the sky. This is true. However; to be more specific solar noon is half way between sunrise and sunset. It's at solar noon that a point gets the most direct sunlight of the day. To calculate solar noon you find out how many hours of daylight there are between sunrise and sunset and divide by 2. Add the quotient to the sunrise time and that will give you the solar noon time.

The sun can never be higher in the sky at the north pole than it is in the sky at New York City. The highest solar noon elevation at the north pole is 23.5 degrees, on June 21. On the same date, the solar noon elevation in Manhattan's Central Park is about 73 degrees.
