1 because negative 4 plus 5
this is an example of linear equations is one variable
Answer:
.
Step-by-step explanation:
All coterminal angles of an angle
are defined as
or 
where, n is an integer.
The given angle is

So, all coterminal angles of an angle
are

For n=1,




Since,
between 0 and 2π, therefore, the required coterminal angle is
.
4
You can just put this into a calculator:
1/2^2 = 0.25
3×5-3 = 12
1^3 = 1
0.25 × 12 + 1 = 4
