The length of one side of a triangle is 3 feet less than twice the length of its second side. The third side is 2/3 of the sum of the lengths of the first 3 sides. Find the length of all three sides if the perimeter is 6.5
+37146 The length of one side of a triangle is 3 feet less than twice the length of its second side. The third side is 2/3 of the sum of the lengths of the first 3 sides. Find the length of all * two * sides if the perimeter is 6.5
Sides a +b + c = 6.5
a = 2b-3
b
c = 2/3 (b + 2b-3)
2b-3 + b + 2/3 (b + 2b-3) = 6.5 first solve for 'b' then a = 2b-3 etc......
The length of one side of a triangle is 3 feet less than twice the length of its second side. The third side is 2/3 of the sum of the lengths of the first 2 sides. Find the length of all three sides if the perimeter is 6.5 feet.
x + (2x - 3) + 2/3(x + 2x - 3) = 6.5
x = 2.3
a = 2.3 b = 1.6 c = 2.6
