Question

given 43 and 62 as the lengths of two sides of a triangle, find the range of values for the third side. enter the number that belongs in the green box

Explanation:

Step1: Determine lower - bound

The length of the third side of a triangle must be greater than the difference of the other two sides. So, $62 - 43=19$.

Step2: Determine upper - bound

The length of the third side of a triangle must be less than the sum of the other two sides. So, $62 + 43 = 105$.

Answer:

$19$
