Question

please solve all this question if the answer will correct and helpful i will add to the brainlist answer

Answer 1

X + X+1 + X +2 = 48
3x = 48-3= 45
X = 45/3= 15
first side= 15
second side= 15+ 1 = 16
third side= 15+2 = 17

Answer 2

let the sides be x,x+1,x+2
perimeter of triangle =side +side + side
48=3x+3
48=3(x+1)
16=x+1
x=16-1
x=15
sides are 15cm,16cm,17cm
