ABC is a triangle such that AB=10 cm and AC=3 cm. Then side BC is
We know that sum of two sides of a triangle is always greater than the third side.
AC + BC should be greater than AB, which is 10 cm.
i.e., AC + BC > 10
Given, AC = 3 cm
⇒ 3 + BC > 10
⇒ BC > 10 - 3
⇒ BC > 7
⇒ BC should be greater than 7 cm.
