The steps are as follows...
* Obviously draw a triangle
* Insert angle bisector for each angle of the tri. Insert the lines & make sure that your long to the point where you can see the point of intersection of the 3 lines.
* Based off that we can already say that Amy is definitely right & the procedure is right but we need two more steps so..
* Insert a line perpendicular to a side that goes through the intersection point if that makes sense. Make …show more content…
Based off what I drew we have twenty angles in the circle & now we need to know what does 1 angle measure up to & that is 360 over 20 equals 18. What we do now is use the formula for the arc length & that will come but first the number eighteen represents the measure of the arc that is the same to basically the central angles measure. Based off that we have to discover the arc's length & the arc length is 7.85.
18 over 360 times pi times r ^ 2 equals 98.17
So based off the question we can logically say that the equation of the circle is provided with the following ( x minus h ) ^ 2 plus ( y minus k ) ^ 2 equals r ^ 2 & this is where the letter r represents the radius & the letters h & k represents the coordinates of the center. Since we have to include something that's like ( x minus h ) ^ 2 what we have to do is basically discover a number that we can use addition for & that is x ^ 2 plus 4x & x ^ 2 plus 4x plus 4 transforms to x plus 2 ^ 2. For the y we want to use addition for y ^ 2 minus 6 y & y ^ 2 minus 6 y plus 9 transforms to x minus 3 ^ 2. Because of the fact that we used addition for 4 plus 9 which was to the left of the equation, now we have to use addition & do the same thing to the right which after doing that it gives you negative 4 plus 4 plus 9 equals 9. Lastly, the equation
