Answer:
B
Step-by-step explanation:
Using the expansion
tan(x - y) =
, then
tan(x -
)
= ![\frac{tanx-tan(-\frac{\pi }{3}) }{1+tanxtan(-\frac{\pi }{3}) }](https://tex.z-dn.net/?f=%5Cfrac%7Btanx-tan%28-%5Cfrac%7B%5Cpi%20%7D%7B3%7D%29%20%7D%7B1%2Btanxtan%28-%5Cfrac%7B%5Cpi%20%7D%7B3%7D%29%20%7D)
note that tan( -
) = - tan(
) = - ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
= ![\frac{tanx-(-\sqrt{3}) }{1+tanx(-\sqrt{3}) }](https://tex.z-dn.net/?f=%5Cfrac%7Btanx-%28-%5Csqrt%7B3%7D%29%20%7D%7B1%2Btanx%28-%5Csqrt%7B3%7D%29%20%7D)
=
→ B
Answer: 57.5
Step-by-step explanation: The first thing you need to know about the order of operations is that multiplication and division come before addition and subtraction.
So in this problem, we are going to divide before we add.
Since 30 divided by 4 is 7.5, our next step will read 50 + 7.5 and 50 + 7.5 simplifies to 14.
