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
