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.
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 are the Advantages of a sextant?
A sextant is an instrument used to measure the angle between two visible objects. It is primarily used as a navigational instrument to determine the elevation of a celestial body above the horizon thereby allowing the observer to calculate a line of position (LOP) on the surface of the earth. With only one LOP, a navigator can be sure that his position is on that line somewhere, but he cannot know for sure where on that line he is. By combining additional LOPs (triangulation), navigators are able to determine their exact latitude and longitude.
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 can you determine your latitude in the northern hemisphere just by using a star?
The angle between the north star and your northern horizon is approximately the same as your latitude north of the equator.
What is angle measured above the altitude?
Altitude is the angle measured above the horizon.
Line that forms a right angle with the horizon?
right angle
Are quadrants still used if so what for?
Quadrants and sextants are still used but to a much lesser degree since the introduction of electronic instruments and satellite GPS systems were introduced. Quadrants/sextants are instruments used to measure angles in surveying and navigation. Using trigonometry when surveying, measuring an angle and knowing the length of a side and another angle of a triangle other distances and angles can be calculated. In navigation, measuring the angle of a star from the horizon and using a set of tables and an accurate time piece your position can be calculated.
What is the impact of Islams contributions of astronomy?
Islamic sailors used to use a navigational tool called a sextant that measured the angle from the sun to the horizon, thereby letting the ship's navigator know how much distance was left between his location and a destination.
What is the function of a sextant?
Sextant is used to measure the angle between any two visible objects.Its primary use is to determine the angle between a celestial object and the the horizon which is also know as objects altitude.
