Answer:
<u><em>8(cos270° + i sin270°)</em></u>
Step-by-step explanation:
(cos(a) + i * sin(a)) * (cos(b) + i * sin(b)) = cos(a + b) = i * sin(a + b)
2 * 4 * (cos(270) + i * sin(270))
8(cos270° + i sin270°)
The total mass for proton is -7.3 and the mass of the electron is 63.1. I'm sorry, I don't get the second part of the question.
Answer:
∠LOA≅∠LMA
