Answer: (-1π) / 3 is in quadrant 4 with reference angle π/3

               9π/4 is in quadrant 4 with reference angle π/4

               -7π/6 is in quadrant 3 with reference angle π/6

                7 (radians) is in quadrant 1 with reference angle 2[tex]\pi[/tex] - 7

Step-by-step explanation:

Given data,

                θ = -1[tex]\pi[/tex]/3

                θ = 9[tex]\pi[/tex]/4

                θ = -7[tex]\pi[/tex]/6

                θ = 7

The reference angle for an angle drawn in standard position (initial side is the positive x-axis with vertex at (0,0)) is the acute angle formed by the terminal side of the angle and the x-axis.  

These formulas are in radians.

                     θ = (-1pi) / 3

                     θ = -180/3

                    θ = -60

So, this is 4th quadrant

                    θ = -45º

So, this is 4th quadrant

                    θ = -210º 3rd

So, this is 3rd quadrant

7 (radians) is in quadrant 1 with reference angle 2[tex]\pi[/tex] - 7

(-1π) / 3 is in quadrant 4 with reference angle π/39π/4 is in quadrant 4 with reference angle π/4-7π/6 is in quadrant 3 with reference angle π/67 (radians) is in quadrant 1 with reference angle 2[tex]\pi[/tex] - 7
