30+40+x = 130 cm( perimeter is the sum of all sides)
therefore, x= 130-70
so x = 60 cm
30+40+x = 130 cm( perimeter is the sum of all sides)
therefore, x= 130-70
so x = 60 cm

perimeter = sum of all sides
let's the 3rd side be x
130 = 30+40 +x
130-70=x
60=x
let's the 3rd side be x
130 = 30+40 +x
130-70=x
