You can go full 2π rotate around counterclockwise so the angle wouldn't be negative.
So -π/2 + 2π = -π/2 + 4π/2 = 3π/2
So (4, 3π/2) is the same point as (4, -π/2)

Answer:
(20 - 24)/6
Step-by-step explanation:
We have the algebraic expression
6(x + 4)= 20
We expand the brackets
6x + 24 = 20
Collect like terms
6x = 20 - 24
x = (20 - 24)/6
A correct solution to the expression is
(20 - 24)/6
Answer:
x minus four

Answer:
<h2><u><em>
x = √95</em></u></h2>
Step-by-step explanation:
from the sign on the picture it is a rigth triangle
we use pythagoras
x² = 12² - 7²
x² = 144 - 49
x² = 95
x = √95
(x = 9.75)
