Let x be the length of the first side:
x = first side
x+10 = second side
2x+6 = third side
Now set up an equation:
x+x+10+2x+6 = 60 (because three sides add up to 60)
4x + 16 = 60
4x = 44
x = 11
So the length of the first side is 11
the length of the second side is 21
the length of the third side is 28
