Question

two equal side of a triangle are each 4m less than three times the third side.find the dimensional of a triangle.if its perimeter is 55m

Answer 1

Answer:

17,17,21

Step-by-step explanation:

let small side be x

therefore, the perimeter =x+x+x+4=55(given)

therefore, 3x+4=55

3x=51

x=17

therefore the two equal is in length=17m

and the longest side is=x+4=17+4

                                        =21m
