Question 1102709
.
<pre>
First side + second side + third side = 176       (<U>the perimeter</U>)


x          + (x+25)       + (x-5)      = 176


x + (x+25) + (x-5) = 176  ====>


3x + 20 = 176  ====>  3x = 176 - 20 = 156  ====>  x = {{{156/3}}} = 52 cm.


<U>Answer</U>.  First side is 52 cm.  Second side is  52 + 25 = 77 cm.  Third side is 52 - 5 = 47 cm.


<U>Check</U>.   You need to check that ALL THREE TRIANGLE INEQUALITIES for the side lengths are satisfied.

         I leave this check to you.
