All right, we're given two sides and the included angle of a triangle asked to find its area.
00:09
Well, that's a formula.
00:11
So the area is going to be equal to, and it's one -half times a times b, times the sign of c.
00:20
All right.
00:21
And so, you know, we can call this guy the a, this guy, it would be the b side.
00:26
This would be the c side.
00:28
And so this is the angle c that we're referring to in that formula.
00:31
All right, so that's not too bad to use.
00:34
We just say it is one half times and my a value.
00:38
I'll put in the eight for that one.
00:40
Times my b value, that's the seven, and then times the sign of the angle c, which is that 28 degrees...
