Question

two equal sides of a triangle are each 5less than twice the third side . Perimeter of triangle is 55m.find tye length of its sides​

Answer 1

Answer:

Step-by-step explanation

let 3rd side be x

ATQ

perimeter of a triangle= sum of all side

55=2(x-5)+2(x-5)+x

55=2x-10+2x-10+x

55=5x-20

55+20=5x

75=5x

15=x

2(x-5)                             2(x-5)                       x=15m

2(15-5)                             2(15-5)                  

2(10)                                2(10)              

20m                                  20m                

Answer 2

Answer:

Step-by-step explanation:

let the third side be x

equal sides=2x-5

perimeter=55m

we know that,

preimeter=sum of all sides

55=x+(2x-5)+(2x-5)

55=x+2x-5+2x-5

55=x+2x+2x-5-5

55=5x-10

5x=55+10

5x=65

x=13

2x-5=2*13-5

       =26-5

       =21

so the sides are 13m, 21m and21m
