Question

The sum of the lengths of two sides of a triangle must be greater than the third side. The sides of a triangle measure x cm, 12 cm, and 10 cm. Which inequality can be used to represent the possible values of x?

x + 12 greater-than 10

x + 12 less-than 10

x + 12 greater-than 12

x + 12 less-than 12

Answer 1

a

Explanation:

Answer 2

x+12 greater than 10

Explanation:

Given

sides of a triangle measure x cm, 12 cm, and 10 cm

In the solution sum of two sides taken is side with length x and 12

using the concept given

sum of the lengths of two sides of a triangle must be greater than the third side.

sum of two sides with x cm and 12 cm = x+12

third side is 10cm

according to concept

x+12 should be greater than 10

x+12 greater than 10

Thus, correct option is first one x+12 greater than 10.
