Best ResponseYou've already chosen the best response.0yup. i'm so lost because i thought triangles are suppose to equal 180.

Best ResponseYou've already chosen the best response.1I'm thinking its 18... Its been forver since i've done this... 4+17 = 21 417 = 13 & the number has to be between 13 & 21 if im thinking right... & 18 is the only up there. does it let you know if its right or wrong?

Best ResponseYou've already chosen the best response.0>yup. i'm so lost because i thought triangles are suppose to equal 180. 180 is the sum of the three interior angles of the triangle. This problem deals with segments.

Best ResponseYou've already chosen the best response.0Use the Triangle Inequality Theorem: One side of a triangle is less than the other two but greater than the positive differeence of the other two.

Best ResponseYou've already chosen the best response.0So, (17  4) < CA < (4 + 17) 13 < CA < 21 @KKKKiaa
