Alright, let's do one more of these. y=12, but if you plug 12 into 4y-6+7y-7, you get 119, and if you do 20y-11, you get 229. The line segment of a circle can either be the diameter of a circle when the line passes through the center of the circle or a chord if the line passes any other place apart from the center of a circle. And we care. So no they cant be line segments so for example: . no because a circle is always gonna be a 360 degree angle. This is a major arc they're talking about. Don't worry about that addition. For the first question if arc AC is the minor arc, then what would be the major arc? this is the other ray. We care about this An exterior angle of a circle is an angle whose vertex is outside a circle, and the sides of the angle are secants or tangents of the circle. If we know the circumference of a circle as well as the arc length, then the ratio between the arc measure and (or depending on whether you want the arc measure in degrees or radians) is equal to the ratio between the arc length and the circumference. So this angle right over here has a measure of 147 degrees and you can calculate, that's the same thing as over here. all angles seem the same. The resulting answer is written in radians, and can be converted to degrees by multiplying that number of radians by 180, then dividing by 3.14 (pi).

Angles formed outside of a circle by any two segments: subtract the smaller arc from the larger arc and then divide by 2. straight up like this. So if this one on, this one is 93 degrees, then this entire blue one right over here is also gonna be, let me write it, this is also gonna be 93 degrees. Secant line segments touch the circumference of the circle at any two points, while chords require their two endpoints be directly on the circle's circumference. So let me draw CE, so CE is, we're going to connect point C and E. These are diameters. An arc's length is the measurement of that arc along and around the outer edge, or circumference, of the circle. I encourage you to Direct link to Deacon's post It looks like a circle. So we're going to have 180 degrees, plus 69 degrees which is equal to, what is that, 249, 249 degrees. As you can see, this gives us 75 degrees for our answer. BC would be the name of the minor arc. But anyway, this has just been both sides to get rid of that - 12 right over there, and So you have In the first example, no, because we don't have expressions for all of the angles, just two of them. And the notation is 360, and In geometry, the arc measure is the arc length divided by the radius. That's one ray of the angle. Here are some of the common angles which you should recognise. And at this point Well, we know, let me write this down. Multiply the area by 2 and divide the result by the central angle in radians. It gets complicated, but here is what I found. at this whole angle, the angle that intercepts The vertex is the center of the circle. Solution: Length of the arc = 11 inches. For the second example, the question says that both AD and CE are diameters of circle P, and I was a bit confused because if both of them are diameters, wouldn't that split the circle into fourths that all equal 90 degrees? here, it would be 0 degrees. They intersect there and there. To find the length of the arc, multiply the radius (6 in) by the measure of the central angle in radians. That's what we're going to try to solve for. Find the measure of the exterior angle, x? Other lesser-known lines include tangents, secants, and chords. So the formula for this particular pizza slice is: An arc angle's measurement is shown asmABm\overset\frown{AB}mAB whereAandBare the two points on the circle creating the arc. degrees plus 69 degrees. right on the right.
