The measure of the third side of the triangle

Answer to Problem 60STP
The measure of the third side of the triangle is
Option A is correct
Explanation of Solution
Given information:
The perimeter of a triangle DEF is
Concept used:
Perimeter of triangle
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Rules of Multiplication/ Division:
- The product/quotient of two similar sign numbers is always positive.
- The product/quotient of two numbers with opposite signs is always negative.
Calculation:
In order to find the measure of the third side of a triangle will be shown below
Thus, the measure of the third side of the triangle is
Option A is correct
