The first box would be 2 and the second box would be 11.
49-65=2(3-11)
-16=2(-8)
-16= -16
Answer: 
Step-by-step explanation:
For this exercise you need to remember the following Trigonometric Identity:

You must observe the figure given in the exercise.
You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).
So, you can identify in the figure that:

Knowing these values, you can substitute them into
:

Now you must evaluate:

Finally, rounding to the nearest hundreth, you get:
