Can 9, 7, 17 make a triangle

No

Step-by-step explanation:

Use Pythagorean theorem a^2 + b^2 = c^2. The way to solve it is 9 squared which is 81 plus 7 squared which is 49 and you get 130. square root 130, if its not 17 then its not a triangle. Hope this helps :)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

0.02
