it would be 30 degrees
It is 15 degrees.
(360 degrees/24 hours = 15).

How many degrees in a right angle in a straight line and in a full circle?
There are 90 degrees in a right angle There are 180 degrees on a straight line There are 360 degrees in a full circle
Is a right angle 60 or 90 degrees?
The definition of a right angle is one quarter of a circle. If you're using the popular system of 360 degrees in a circle, then a right angle is 90 degrees.
Can a right angle equal 180 degrees?
No. A right angle is defined to be 90 degrees.
How do we measure an angle?
A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.
What is the degress of a square?
The degrees of a square is 360 degrees. A square has four equal angles, each measuring 90 degrees.
How many minutes of arc are equivalent to 1 minute of right ascension?
Right ascension is expressed in units of time; one hour is equal to 15 degrees, so a minute of right ascension is equal to 1/4 degree, or 15 arc-minutes.
One hour of right ascension is equivalent to how many degrees of sky rotation?
Depends on the declination in question. There are 24 hours of right ascension in 360 degrees, so at the celestial equator (declination = 0 degrees) 1 hour of right ascension is equal to 15 degrees. But as you increase or decrease declination the right ascension lines converge to the celestial pole (like longitude lines on a globe). The angle covered by 1 hour of right ascension is therefore equal to (15 degrees x cos(declination) ), so at the celestial poles (declination = +/- 90 degrees) 1 hour of RA is 0 degrees.
What does D in a R A mean?
90 degrees in a right angle or Ninety degrees in Right Ascension = celestial coordinate.
What does 90-D in a R A mean?
90 degrees in a right angle or Ninety degrees in Right Ascension = celestial coordinate.
What does '90 D in a R A' mean?
90 degrees in a right angle or Ninety degrees in Right Ascension = celestial coordinate.
What are some fascinating facts about Sagittarius?
the right ascension is 19.11h and the declination is -25.8 degrees
If a right angle takes up 90 degrees of a circle how many degrees is the rest of the circle?
270 degrees
How many degrees in a right angle in a straight line and in a full circle?
There are 90 degrees in a right angle There are 180 degrees on a straight line There are 360 degrees in a full circle
Is a right angle 60 degrees?
No, it's 90. A right angle is 25% of a full circle, (or 1/4 of a circle) ......... if a full circle is 360 degrees around, then a right angle, being 1/4 of that, must be 90 degrees.
Is a right angle 60 or 90 degrees?
The definition of a right angle is one quarter of a circle. If you're using the popular system of 360 degrees in a circle, then a right angle is 90 degrees.
How do you spell ascension?
Ascension, you spelt it right.
Is mercury in the right ascension?
"Right ascension" is just one number for the coordinates of a planet, star, etc. Any such object has a right ascension.
