00:00:00,550 --> 00:00:06,790
Let's do this question the length of two sides of a triangle are seven and nine centimeter.

2
00:00:07,120 --> 00:00:11,070
The length of the third side may lie between both the video.

3
00:00:11,230 --> 00:00:13,400
Give it a try and then let's do it together.

4
00:00:13,900 --> 00:00:14,400
All right.

5
00:00:14,620 --> 00:00:22,630
We know that if A, B and C are three sides of a triangle, then A minus B has to be less than C and

6
00:00:22,630 --> 00:00:25,760
C has to be less than A plus B, right.

7
00:00:25,960 --> 00:00:27,300
So let's try that over here.

8
00:00:27,460 --> 00:00:29,590
We have two sides, seven and nine.

9
00:00:29,740 --> 00:00:36,100
So nine minus seven has to be less than the third side and the third side has to be less than nine plus

10
00:00:36,100 --> 00:00:36,490
seven.

11
00:00:36,770 --> 00:00:42,750
So that means two centimeters, less than the third side, less than 16 centimeters.

12
00:00:43,120 --> 00:00:46,660
That gives us our answer, which is option C.

13
00:00:46,810 --> 00:00:50,540
And remember, the third side cannot be two or 16, right?

14
00:00:50,710 --> 00:00:54,130
It can be three or extra up to 15.
