Question

A triangle has two sides of length 7 and 9. What value could the length of the third side B? Check all that apply.

A.8
B.5
C.22
D.13
E.2
F.10

Answer 1

A ; B ; D ; E ; F

Explanation:

• Triangle Inequality Theorem

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

7 + 9 = 16

16 > 8 ; 5 ; 13 ; 2 ; 10

Answer 2

8, 5, 13, 10

Explanation:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
