In this problem, our ultimate goal is to find the area of triangle g, h, j.
00:04
So let's go ahead and draw this triangle.
00:07
So if i have triangle g, h, j, we can now go ahead and label it.
00:12
Well, we know that angle g is 135 degrees.
00:15
Side h, which is opposite angle h, is equal to 8.
00:18
And side j, which is opposite to angle j, is 15.
00:22
Well, we're given two sides in the included angle.
00:25
We have a formula to allow us to find the area of this type of triangle.
00:28
Its a is going to equal 1 1�t times the product of the adjacent size, so in this case, h times j, times the sign of the included angle, which is angle g...
