Can anyone answer this I need it ASAP plz
Pani-rosa [81]

Answer: x = 13.4

Step-by-step explanation:

1. Subtract 90 degrees and 33 degrees to get angle X, which is 57 degrees.

2. Using Laws of Sine, plug in the known elements of the triangle:

(16) / (sin(90)) = (x) / (sin(57))

3. Cross multiply, this will leave 16sin(57) = xsin(90)

4. Divide sin(90) to the other side, leaving x = (16sin(57)) / (sin(90))

5. Plug this into a calculator and your final answer should be 13.4
