DeMoivre's theorem says
(2 (cos(12°) + <em>i</em> sin(12°)))⁵ = 2⁵ (cos(5×12°) + <em>i</em> sin(5×12°))
… = 32 (cos(60°) + <em>i</em> sin(60°))
… = 32 (1/2 + √3/2 <em>i</em> )
… = 16 + 16√3 <em>i</em>
Answer:
The value of x is 8
Step-by-step explanation:
100% of 120 = 120
50% of 120 = 60
350% of 120 = 120 + 120 + 120 + 60 = 420
There were 420 shoppers after the special.
