Answer 1

Answer:

One side is 17cm

Second side is 10cm

Third side is 22cm

Step-by-step explanation:

Let the third side be x . One side is x-7 , another side is x+5 . We know that perimeter of triangle is 49cm.

x+x-7+x+5=49

3x-2=49

3x=49+2

x=51/3

x=17

One side is 17cm

Second side is x-7=17-7=10

Third side is x+5=17+5=22.

Hope this helps.
