Hello, hi students.
00:01
Let me explain to the question here.
00:03
We have to find the length of the side.
00:06
Find the length of the side labeled x.
00:10
Label x.
00:13
So here, so here we have to find this x value and here in this figure we have to find the x value.
00:23
So here the tan 39 degrees.
00:28
So the tan 39 it will be the opposite side by adjacent side.
00:35
So the opposite side let it be h.
00:39
So that is h by 38.
00:42
So 38, 10, 10, 39 degrees it will be h.
00:48
So that is equal to h is equal to 30 .77.
00:54
So here, h, it will be 30 .77.
00:59
Now, by using, by using cos cos theta...
