When we need to find the angle, we use the inverse. This will have a -1 above the function.
EX: sin-1
We need to use whats given to us, or the sides given. This problem has a number on the adjacent side, and one on the opposite side. So we are going to use Tangent, or TAN.
tan-1 (300/400)
Note: When plugging this into your calculator, make sure to use parentheses around the numbers used
