A triangle has a perimeter of 15 feet. Side B is one foot longer than side A. Side C is two feet longer than side A. What is the length of each side.

Answer 1

Side A = 4

Side B = 5

Side C = 6

Explanation:

In the following equation, variable a is the length of Side A

a + (a + 1) + (a + 2) = 15

a + a + a + 1 + 2 = 15

3a + 3 = 15

- 3 - 3

3a (÷ 3) = 12 (÷ 3)

a = 4

Side A = 4

Side B = (a + 1) = (4 + 1) = 5

Side C = (a + 2) = (4 + 2) = 6
