A SEXTANT.
It is an instrument of two mirrors, where the angle can be adjusted.
The observer puts his eye to the eye glass, to see the two mirros. He first observes the given star, through one glass. Then adjusts the angle so he can see the horizon through the other glass. So he is seeing both the given star and the horizon. The given angle between the two mirrors will be used to estimate the latitude for navigational purposes.
If the SUN is used as the observational star, then 1; a darkened mirror is used , to avoid blindness, and 2 ; the angle measured is the latitude.
What else can I help you with?
Explain what the measure of an angle is?
the measure of an angle is the degrees of an angle.
What is the measure of the supplementary angle of an interior angle?
The measure of the exterior angle.
Find the measure of angle and if the measure of angle abc60 the measure of angle and is represented by 5x 7 and the measure of angle dbc is represented by 9x-3?
No cheating!
When 15 is subtracted from the measure of an angle the result is the measure of a right angle what is the measure of the original angle?
15
In a parallelogram the measure of angle b the measure of angle a by 30 degrees what is the measure of angle d?
105 degrees
How did Captain Ahab check the angle of the sun?
Captain Ahab checked the angle of the sun by using a navigational instrument called a quadrant. This tool allowed him to measure the angle of the sun above the horizon and determine the ship's position.
What is the navigational tool to find latitude?
The navigational tool to find latitude is a sextant, which uses the angle of the sun or stars above the horizon to determine the observer's position on Earth. This angle corresponds to the observer's latitude.
You can measuring the altitude of a star by measuring the angle between your horizon and the star using a?
We would typically use a sextant to measure the angle of a star above the horizon.
How you can tell when a angle is 200 degrees?
There are special angle-measuring instruments which you can use to measure the angle.
What century was the sextant invented?
The sextant was invented in the 18th century, with its development attributed primarily to the work of John Hadley and Thomas Godfrey in the 1730s. This navigational instrument allowed sailors to measure the angle between celestial bodies and the horizon, significantly improving maritime navigation. The sextant evolved from earlier instruments like the quadrant and astrolabe, and it became an essential tool for navigation at sea.
What were the instruments that Greeks used to measure angle and long distances?
triquetrum.
What kinds of navigational instruments did Renissance explorers use?
Renaissance explorers used several key navigational instruments, including the astrolabe, which helped determine latitude by measuring the angle of celestial bodies above the horizon. The compass, essential for orienting direction, became widely used during this period. Additionally, the quadrant and later the sextant enabled more precise measurements of celestial positions. These tools significantly improved navigation, allowing explorers to venture further into uncharted waters.
What do you use to measure the angle of a star?
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
Why was the cross staff important?
The cross staff was important in navigation during the late Middle Ages and the Renaissance because it allowed sailors to measure the angle of celestial bodies above the horizon. This tool enabled navigators to determine their latitude with greater accuracy while at sea. By aligning the cross staff with the celestial object and the horizon, sailors could take reliable readings, which significantly improved maritime navigation and exploration. Its use laid the groundwork for more advanced navigational instruments that followed.
How do you measure sunset?
The sunset is typically measured by the angle of the sun as it disappears below the horizon. This angle can vary depending on your location and the time of year. One common way to measure sunset is using degrees above the horizon or by using a specific almanac or app.
Who invented and used the first sextant?
The sextant was developed in the 18th century, with significant contributions from several inventors. The first practical sextant is attributed to British instrument maker John Hadley, who created a working model around 1730. However, the design was also influenced by earlier navigational instruments such as the quadrant and the astrolabe. The sextant became widely used by sailors for celestial navigation, allowing them to measure the angle between a celestial body and the horizon.
Used to to take bearings from the sun or stars to plot the ships position on a map?
Navigational instrument or tool such as a sextant or astrolabe is used to measure the angle between a celestial body (sun or stars) and the horizon. This information helps determine the ship's position on a map by calculating latitude and longitude coordinates.
