Try this: Combine 6 and 9, obtaining 15.
Compare this sum, 15, to the length of the 3rd side: 15.
If placed end to end, the 2 sides with lengths 6 and 9 form a new line of length 15. We'd end up with this new line superimposed on the 3rd side (with length 15).
Think: Do 2 straight lines of length 15, superimposed on one another, form a triangle?

I took a19=-58 divide it by 19 both side i get a = -58÷19 (note; you can never have a neg. # on the top bring the neg. down to the bottom and divide) now its 58÷-19= -3.05 or -3 (1÷19) so a = -3(1/19) do the same to the other now. answer is a=-7 (17/21)
