Question

Determine if the three lengths can be the measures of the sides of a triangle.

3 in, 9 in and 8 in

Answer 1

yes

Explanation:

For the lengths to form a triangle, the sum of any 2 must be greater than the third, that is

3 + 9 = 12 > 8

3 + 8 = 11 > 9

9 + 8 = 17 > 3

Thus the 3 lengths can form a triangle
