you take the degree that you already have and subtract it from 360 and if you don't already have a degree try to weasel it out of your teacher

What is the unit circle?
The unit circle is a circle that can be used to find trigonometric functions. The equation of the unit circle is x^2 + y^2 = 1. So it is any circle with radius 1.
Find all the coordinates of the points on unit circle?
If x2 + y2 = 1, then the point (x,y) is a point on the unit circle.
When was it confirmed that there was 360 degrees in a circle?
It was never confirmed. The degree was created as a unit equal to one three hundred sixtieth of the way around a circle
What is the unit used to measure distances around a circle?
The distance around a circle is its circumference and it can be measured in any linear units.
Which best describes how to find the length of an arc in a circle?
Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
Can the unit circle have a radius of 2 unit?
If the radius is two. it won't be a unit circle, a unit circle is defined as a circle with radius one.
How can one calculate the area of a unit circle?
To calculate the area of a unit circle you should use the equation x2+y2=1. The unit circle equal area of 1. You can find out more information on the mathisfun website for deeper explanation.
What is unit circle?
The unit circle is a circle with its center at the origin and a radius of ' 1 '.
How is cos 90 equal to 0?
The Unit Circle is a circle that has a radius of 1 and a center at the origin. If you look at the unit circle 90 degrees is at the point (0,1). Cosine is equal to the x value of a point on the Unit Circle. The line created to the point (0,1) on the unit circle when the degree is 90 is completely vertical, which in turn makes the x value 0 and thus, cosine of 90 = 0.

How do you find the arc length with the angle given?
An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.
How many units in a unit circle?
A unit circle is a circle with radius equal to one.
Find the area of a sector in a circle if the radius is 4 cm and the arc has degree 120?
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
