1 answer:

5 0

As far as I can tell you are correct. The correct answer for x should be
-pi/3

If you plug x=+pi/3 into the expression cos(x/2 + pi/6), it ends i equaling 1/2, not 0.

FromTheMoon [43]

Answer:

Step-by-step explanation:

Solve the inequality by using inverse operations.

Like solving equations, inequalities should be solved using inverse operations. However, unlike equations, when you divide or multiply by a negative the sign changes.
