Distance formula between 2 points (x1,y1) and (x2,y2)
D=

D=29 and one point is (-5,5) and the other is (k,0)
sub
29=

29=

square both sides
841=

841=

minus 25 both sides
816=

square root both sides don't forget positive and negative roots
+/-4√51=-5-k
add 5 to both sides
5+/-4√51=-k
times -1 both sides
-5+/-4√51=k
the possible values for k are
k=-5+4√51 or k=-5-4√51
