Question from Susan, a student: The second side of a triangle is 5ft more than the length of the first side. The third side of the triangle is 10ft less than the length of the first side. |
Susan,
Let the length of the first side be x feet. The length of the second side is 5 feet more that this so it's x + 5 feet. What is the length of the third side? What is the sum of the lengths of the three sides? Solve for x.
