Answer:
11π/4
Step-by-step explanation:
Coterminal angles have the same terminal sides when they are in standard position.
To find a positive angle that is coterminal with
We add 2π
This means , a positive angle that is coterminal with 3π/4 is
Answer:
z = -5
Step-by-step explanation:
add 9z to both side giving you ---> 18z+93 = 3
now subtract 93 from both sides ---> 18z = -90
now divide 18 by both sides and get your z
So, for number 3, its 2. and for number 4 its also 2
