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 o
f the lengths of the first 3 sides. Find the length of all three sides if the perimeter is 6.5
1 answer:
Answer:
side 1: 1.6
side 2: 2.3
side 3: 2.6
Step-by-step explanation:
side 1: 2x - 3
side 2: x
side 3: 2/3(x + 2x - 3) = 2x-2
(2x - 3) + x + (2x - 2) = 6.5
5x - 5 = 6.5
5x = 11.5
x = 2.3
side 1: 1.6
side 2: 2.3
side 3: 2.6
