Solve.The first side of a triangle is 10 feet longer than the second. The third side is 12 feet less than double the second. The perimeter of the triangle is 90 feet. Let s represent the length of the second side and define the variable expressions in terms of s for each of the three sides.
A. length of first side = s - 10 length of second side = s length of third side = 2s - 12 B. length of first side = s + 10 length of second side = s length of third side = 12 - 2s C. length of first side = s - 10 length of second side = s length of third side = 2(s - 12) D. length of first side = s + 10 length of second side = s length of third side = 2s - 12
