## How many degrees is an angle?

The concept of angle The more familiar unit of measurement is that of degrees. A circle is divided into 360 equal degrees, so that a right angle is 90°.

## How many inches is 360 degrees?

So the number of degrees per inch depends on the size of the circle, or sphere. For instance, if I draw a circle with a radius of 1 inch, then 360 degrees (all the way around the circle) corresponds to 2π inches, about 6.283 inches. So each degree is about 0.0175 inches.

## How do you convert angles to degrees?

To convert radians to degrees, multiply the radian by 180/ π. So, the formula is given by, Angle in radian x 180/ π = Angle in degrees.

90° π/2 1.571
180° π 3.142
270° 3π/2 4.712
360° 6.283

## What is the reference angle for 200o?

A 240-degree angle is between 180 and 270 degrees, so its terminal side is in QIII. Do the operation indicated for that quadrant. Subtract 180 from 240. You find that 240 – 180 = 60, so the reference angle is 60 degrees.
