can you help me with this ?? i think its the second answer The equation of a circle is (x + 3)2 + (y – 5)2 = 81. Determine the coordinates of the center of the circle and the length of the radius. Center (-3, 5), radius is 9 Center (3, 5), radius is 9 Center (-5, -3), radius is 81 Center (5, 3), radius is 81

thought so too @Lui2301

so that's why the center of \[\Large (x+3)^2 + (y-5)^2 = 81\] is (-3,5)

14. anonymous

so its the first one

let x = measure of angle CLA with any quadrilateral, the 4 angles always add to 360 degrees x+90+90+170 = 360 x = ???

25. anonymous

10 ?

26. jim_thompson5910

correct
