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.

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 were the instruments that Greeks used to measure angle and long distances?
triquetrum.
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.
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.
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.
What instrument could sailors use to determine their location based on the position of the sun in relation to the horizon?
Sailors could use a sextant to measure the angle between the sun and the horizon. By comparing this angle with known tables, they can determine their latitude at sea.
How can you determine your latitude in the northern hemisphere just by using a star?
To determine your latitude in the northern hemisphere using a star, measure the angle between the horizon and the star using a sextant. This angle is called the star's altitude. If you know the star's declination (which is constant), subtract it from 90 degrees minus the star's altitude to find your latitude.
What are the Advantages of a sextant?
Sextants are reliable navigation tools for determining the angle between celestial objects and the horizon, allowing sailors to establish their position accurately at sea. They do not rely on electricity or technology, making them dependable in remote areas or during emergencies. Additionally, mastering the use of a sextant can improve navigation skills and deepen understanding of celestial phenomena.
What is angle measured above the altitude?
Altitude is the angle measured above the horizon.
