Remeber ADJACENT means right next to. It is the side that is actually touching the angle that you are looking at. The opposite side is the side that does not touch the angle you are looking at.

Also remember this when you are looking for the length of a side.

If the x is on top you will multiply.

If the x is on bottom you will divide. The tan(number°) will be on the bottom of the fraction.

On the next problems you are looking for the measurement of the angle. These are a lot easier. This is like what we did the day before.

Opposite/Adjacent
is 3/5 in this case. So in the calculator you will use the "inv" button with the "tan" And always remember that you have to have "deg" selected also.

First to setup the ratio it is going to look like this. Opposite over adjacent is going to be 15/x So you get
When the x is on bottom we will dividing. It will end up being
It will look like this in the calculator. Makes sure that you have degree clicked. and that you use just the regular tan without clicking "inv" first.
Here is what the answer is.
