A triangular sail has a perimeter of 25 m. Side a is 2 m shorter than twice side b, and side c is 3 m longer than side b. Find the length of each side.
We know that perimeter of the triangle its a+b+c=25 a=2b-2 b=b c=b+3 Now we can substitute it into our formula 2b-2+b+b+3=25 4b+1=25 /-1 4b=24 /:4 b=6 - its b side a=2*6-2 a=12-2=10 - its a side c=6+3=9 - its c side
