Answer:
Step-by-step explanation:
Here we have the length of the hypotenuse (16) and that of the vertical leg (11). The cosine function inputs this data:
adjacent side 11
sin x = ----------------------- = ---------------- = 0.6875
hypotenuse 16
We find x using the arccos function: arccos 0.6875 = 0.81 radians or
46.57 degrees
