A triangle has two side lengths of 7 and 12. what value could the length of the third side be?

13.9

Step-by-step explanation:

7^2 + 12^2 = c^2

49 + 144 = 193

square root 193

and it’s 13.9

c.

step-by-step explanation: it's not a. because 1/3 x 1/3 x 1/3 = 1/27 so that's not correct. | b. is also not correct because 7 x 7 1/3 is not actually 3 x 7 1/3 . and for d. multiplications are not additions so that left you with c. ( hope this out : d )
