You simply divide 678 by 3 and get 226.
In order to find the solution you just have to answer one of the equations to solve for x then plug it in for the other ones. so lets start. so x equals 1/3
Answer:
See below in bold.
Step-by-step explanation:
cos 150 = - cos(180 - 150)
= - cos 30
= -√3/2.
sin 150
= sin (180 - 150
= sin 30
= 1/2.
Answer:

Step-by-step explanation:
Given the expression:

To find:
The expression of above complex number in standard form
.
Solution:
First of all, learn the concept of
