Find the length of the third side if necessary round to the nearest tenth 8,16
17.9
24
13.9
To find the length of the third side, we can use the triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Given the lengths of the two sides are 8 and 16, we can set up the inequality:
x < 8 + 16
x < 24
Therefore, the length of the third side must be less than 24 units. Since the only feasible answer choice that is less than 24 is 13.9, the length of the third side is approximately 13.9 units.
