1.	Chalienge!The sides of a triangle have lengths (in cm) 11, 7.5 and x, where x is a whole number. The mininvalue that x can take is(a) 6(b) 4(c) 3(d) 5
Answer» In a triangle, sum of two side is always greater than the third side. Therefore, x+ 7.5 > 11 => x> 3.5 since, x is a whole number, therefore x will have minimum value as 4. Ans: Option B is correct
