Answer:
its the first answer choice!
Step-by-step explanation:
the answer is B
6w + 5 - 3w + 7
= 6w - 3w + 5 + 7
= 3w + 5 + 7
= 3 w + 5 + 7
= 3w + 12
a = π n for n element Z
Solve for a:
sec(a) + tan(a) = sec(a) - tan(a)
Subtract sec(a) - tan(a) from both sides:
2 tan(a) = 0
Divide both sides by 2:
tan(a) = 0
Take the inverse tangent of both sides:
Answer: a = π n for n element Z
