So numbers of similar triangles are given we need to find the we need to find the missing side so the let the missing side be x so i'll be representing by x all the missing side by x so similar triangle is so for the first part is a similar triangle so i can write that 3 upon 6 is equal to 5 upon x this implies value of x is equal to this implies value of x is equal to this implies is equal to 10.
00:32
So for the first part the answer comes out to be 10.
00:36
For the first part, answer comes out to be 10.
00:38
Now moving to the second way.
00:41
So again here, here also again applying the same rules since triangle, both triangles are congruent.
00:49
So i can write 9 upon 12 is equals to 18 upon x.
00:56
So this is our x.
00:57
We need to find this.
00:58
So this is, 9 upon 12 is equal to 18 upon x.
01:03
So 3 -0 -3 -6 -4 -za.
01:07
So again, so this implies that x is equal to, this implies that x is equal to 18 into 4 upon 3 and 3 6x is 18.
01:18
So value of x comes out to be 24.
01:20
Value of x comes out to be 24.
01:23
Value of x comes out to be 24.
01:25
This is the second part.
01:27
Now moving to the question number 3.
01:31
So here also there are two triangles.
01:34
So again, using the ratio rule.
01:39
So it would be at 10 upon 6 is equal to 15 upon.
01:46
So this is x, 15 upon x...
