The lengths of the sides of a triangle are 17, 8, and n. Which of the following must be true?

A. 9 < n < 25
B. n > or equal to 25
C. n < 9
D. 9 < or equal to n < or equal to 25

At first I thought it was B, then I thought it was A or D... is it A? Please help? Thanks

• Geometry -

a-b < c < a+b

Looks like A to me.

D is wrong, because if c=9 or 25, the triangle is just a flat line. Try drawing it.
