Question

the isosceles triangle has a base that measures 14 units.
the value of y, the length of each leg, must be
○ equal to 7.
○ between 7 and 14.
○ greater than 7.
○ between 14 and 28.

Explanation:

Step1: Apply triangle inequality theorem

Sum of two legs > base: $y + y > 14$

Step2: Simplify the inequality

$2y > 14 \implies y > 7$

Answer:

C. greater than 7.
