The equation of a circle is (X+12)^2+(y+16)^2=r^2, and the circle passes through the origin. The equation of the circle then cha
nges to ( x-30)^2+(y-16)^2=(r2)^2 and the circle still passes through the origin. What are the values of r1 and r2? Answers: r1 = 10 and r2 = 17 r1 = 10 and r2 = 34 r1 = 20 and r2 = 17 r1 = 20 and r2 = 34
the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements
