Question 1101047
<font color="black" face="times" size="3">
a = 3, b = 10, and c = 9 are the three sides of the triangle.


A triangle is only possible if we can add any two sides to have the sum be larger than the third side


a+b = 3+10 = 13 which is larger than c = 9
b+c = 10+9 = 19 which is larger than a = 3
a+c = 3+9 = 12 which is larger than b = 10
----------------------------------------------
So we've shown that the three inequalities below are true
a+b > c
b+c > a
a+c > b


Meaning that a triangle is possible with these three measurements.
