we know that
The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Let
s------> the length of the third side
therefore
<u>The answer part a) is</u>
we know that
the perimeter of a triangle is the sum of the length sides
In this problem
<u>For </u>
the perimeter is equal to
<u>For </u>
the perimeter is equal to
so
therefore
<u>the answer part b) is</u>
