Question

Find the value of x​

Answer 1

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
