Answer to Question #232 in Geometry for Jane Dawson
The lengths of two sides of the triangle are 3.14 and 0.67. Find the length of the third side if known that it is an integer.
Let the length of the third side be n. According to the triangle inequality: 3.14 - 0.67 < n < 3.14 + 0.67. As n is integer, we can state that n = 3.
