One side of a triangle is for more than twice the second side of a triangle the third side is six less than a second and the perimeter of the triangle is 86. what is the actual measure of each side?

Answer 1

1. Let's define the first side of the triangle:
2. 4 + 2x
3. The second side is x.
4. The third side is x-6
5. Put it all together in an equation equalling the perimeter, 86.
6. 4 + 2x + x + x-6 = 86.
7. 4 + 4x -6 = 86
8. 4x -2 = 86
9. 4x = 88
10. x = 22, the second side
11. The other 2 sides are:
12. First side: 4 + 2x, 4 + 2(22) = 4 + 44 = 48
13. Third side = x -6 = 22 -6 = 16
14. Check your answer:
15. 48 + 22 + 16 = 86
16. 86 = 86
