This is the same stuff you have been doing for the last 4 days. It is just mixing them up together. You will have 45°-45°-90° traingles and 30°-60°-90° triangles. Remember the difference between the two triangle types. The 45°-45°-90° triangles use the square root of 2.
The 30°-60°-90° triangles use square root of 3 and double.
I am attaching 2 of the previous videos that you have already seen if you need to see them again to jog your memory on how to do each type.
