I'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?

>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.

Use 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.

So, (17  4) < CA < (4 + 17) 13 < CA < 21 @KKKKiaa

I saw that you had figured out this problem but wanted to provide the theorem so that you will be empowered to do similar problems. Just saying.
