Asking us to determine if we have two triangles, one triangle, or no triangles.
00:06
And we're given the following information that i typed here in blue.
00:11
So in order to do this, we're going to use the law of signs.
00:14
So i'm going to have the sign of our angle a.
00:22
So i have the sign of 26 .6 over our side a, which is 25 .5, equal to sign of b.
00:33
We don't know over our side b, which is 40 .5.
00:40
Now when i do this, i'm going to cross multiply.
00:43
So we have 40 .5 sine 26 .6 equals cross the other way, 25 .5 sine b.
01:02
Now i'm going to divide both sides by 25 .5 .5.
01:09
And i'm going to put all of that into my calculator at once.
01:17
So i'm going to have 40 .5 sign of 26 .6.
01:23
I like to hit enter and then divide by 25 .5.
01:28
When i do that, we get a long decimal.
01:32
And i like to use that decimal and plug that in to the inverse sign.
01:39
And i use my answer button.
01:41
So the ans button...
