Okay, we are told here, it's a right triangle, and i often use his length of 7, and one angle is going to be 32 degrees.
00:11
So i want to work out x and y.
00:16
I know x is the shorter length because the angle up here will be 58 degrees, to make 180 in total, and smallest side always occurs across from the smallest angle.
00:29
So 32, the smallest angle, x the smallest side.
00:36
So define x first, i'll just use sine.
00:39
Sign 32 degrees, opposite over hypotenuse, x over 7, which means x will be 7 times sine 32.
00:52
And that's i work out.
00:56
And degree mode on the calculator, check that.
00:58
7 times sine 32 is 3.
