The value of y, the length of each leg, must be greater than 7.
<h3>
What is Isosceles triangle?</h3>
This is a type of triangle with two equal sides.
<h3>Rules for side length of triangles</h3>
- The sum of any two sides of a triangle must be greater than the third side.
Let the first, second and third side = a, b and c respectively
(b - a) < c < (a + b)
For an isosceles triangle with base of 14 units, the two other sides must be equal.
c < (a + b)
c = 14
a = b = y
14 < (y + y)
14 < 2y
7 < y
Thus, the value of y, the length of each leg, must be greater than 7.
