The three sides of an isosceles triangle are length of lengths (x + 3), (2x + 3), (2x - 3) respectively. Calculate x.
Answer Details
2x + 3 ≠ 2x - 3 for any value of x ∴ for the △ to be isosceles, either 2x - 3 = x + 3 or 2x + 3 = x + 3 solve the two equations we arrive at x = 6 or x = 0 When x = 6, the sides are 9, 15, 9 When x = 0, the sides are 3, 4, -3 since lengths of a △can never be negative then the value of x = 6
