Question

the perimeter of the triangle shown to the right is 154 meters. find the lenght of each side. (4x)m  (7x+2)m  (7x+8)m

Answer 1

4x + 7x + 2 + 7x + 8 = 154
18x = 154 - 10
18x = 144
x = 8

Sides: 32 m, 58 m , 64 m

Answer 2

The first to find the length of each side, we have to find the value of x :

`(4x) + (7x + 2) + (7x+8) = 154`


`4x + 7x + 7x + 2+8 = 154`


`18x +10 = 154`


`18x = 154 - 10`


`18x = 144`


`x = (144)/(18)`


`\boxed{x=8}`

Solution First side :

`(4x)m = (4 \cdot 8)m = 32\ m`

Solution Second Side :

`(7x+2)m = (7(8)+2)m = 58\ m`

Solution Third Side :

`(7x+8)m = (7(8)+8)m = 64\ m`
