Answer 1

Answer:

Step-by-step explanation:

let the 1st side be x.

x+x-7+x+5 = 49

3x-2 = 49

3x = 49+2

    = 51 cm

x = 17cm

x+5 = 22cm

x-7 = 10 cm

Answer 2

Answer:

The answer is below

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.
