For questions like these, what you want is you want to start by drawing out the triangle.
00:05
So we know that we have a triangle t -u -v, where the angle v is 95 degrees.
00:13
Okay, so let's say that this is my angle v right over here.
00:20
So this angle here is 95 degrees.
00:24
Okay, and then now you can label the rest.
00:26
So let's say this is t and this is u.
00:29
And i'm going to connect them so that i get a triangle.
00:34
So now the other piece of information that we're given is angle t is 10 degrees.
00:39
So that means this angle up here is 10 degrees.
00:42
And now whenever you have two angles inside a triangle, you can always find the third one, because we know that the sum of all angles inside a triangle has to be 180 degrees.
00:53
Right.
00:54
So which means here we have 10.
00:55
Here we have 95.
00:57
So this is already 105.
00:58
So that means this last angle here has to be 75 degrees.
01:05
Okay, and now we're also given that u is 440 inches.
01:12
So naming convention wise, we always name the side after the angle right across from it...
