Three sides of a triangle measures 6 cm, 10 cm and x cm. The minimum integral value of x is :
Answer & explanation
Correct answer: option 4
We know that,
The difference of two other sides < x < sum of two other side
We have,
One side of triangle = 6 cm
Second side of triangle = 10 cm
(10 - 6) < x < (10 + 6)
= 4 < x < 16
The third side of the triangle should lie between 4 and 16
So, the minimum integral value = 5
