I want to solve for x here.
00:04
So for that we have two triangles here.
00:06
I can name the triangles.
00:07
This is let's say, a, b, c, and d.
00:12
So, let's say this is b c here.
00:15
We're taking out triangle a, b, c.
00:18
If i apply some trigonometry, we find b c here, right? so we'll have 1064 as equal to 1064.
00:26
That is equal to we have opposite over adjacent.
00:31
That would be given as a positive.
00:33
Is 390, 390 over adjacent.
00:37
Addison is bc.
00:39
From here we get bc is 390 over 1064.
00:45
So i'm going to use a calculator here and solve this, so let me use that...
