Correct Option:Option B
Solution:The given expression is:

cos(3x) can be written as cos(2x +x). Expanding it, we get:

Using this value of cos(3x) in given equation, we get:
Answer:
2(3x)+2(2x+22)+x+41=360°
Step-by-step explanation:
Sum of exterior angles of any polygon is 360°.
So if we add up all five exterior angles of the pentagon, we have
