Let's say we want to find x first.
00:04
Using the 26 .57 degree angle, we, and the fact that x is adjacent, and we have 8, which is the hypotenuse, we're using, in utilizing sine, cosine, and tangent here, we can say that the cosine of 26 .57 degrees is equal to the adjacent leg over the hypotenuse.
00:28
Multiply both sides by 8, and we've got.
00:30
Which i'll go to two decimal places and i'll record them all under here.
00:38
8 cosine 26 .57.
00:41
Now make sure you are in degree mode and then you can do 8 cosine 26 .57 degrees and that's about 7 .16.
00:57
For y, let's use the 48 .81 degree angle.
01:04
We want to find the hypotenuse and we have the opposite.
01:09
To that angle...
