how do you tell if you need to use tan sin or tan?how do you tell if you need to use tan sin or tan?
It depends on the angles and the sides you have!.
what if i have the hypontenuse and the base
In that case, you would use "Cosine", because:
Cos(x) =Adjacent(base) / Hypotenuse.
so what if my base is 100 but the angle between the hypotenuse and base is 12 what would i use
You use what I told you:
Cos(12) =base(100) / hypotenuse. Take the cos of 12 degrees,
0.9781476 =100 / hypotenuse
Hypotenuse =100 / 0.9781476
Hypotenuse =102.234
