The coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.
<h3>What is coterminal angles?</h3>
Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
We have an angle:
-4π/5
To find the coterminal angle, add and subtract by 2π in the angle -4π/5
Coterminal angle:
= -4π/5 - 2π
= -14π/5
= -4π/5 + 2π
= 6π/5
Reference angle:
= π - 4π/5 (as the angle lies in the second quadrant)
= π/5
Thus, the coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Answer:
<h2>73</h2>
Step-by-step explanation:
The Ruler Postulate:
A distance between a number A and a number B:
AB = |B - A|
We have A = -60, and B = 13. Substitute:
|13 - (-60)| = |13 + 60| = |73| = 73
Answer:
Assuming x is the number, then 
Step-by-step explanation:
If the product of a number and 5 is 8, the equation becomes:
(assuming x is the unknown number).
We can isolate the variable x by dividing both sides by 5.

Answer:
$409.86
Step-by-step explanation:
To find the price after marking it up, 230 x 0.65 = 149.5
230 + 149.5 = 379.5
Usually we add tax after the discount/markup.
379.5 x 0.08 = 30.36
379.5 + 30.36 = $409.86
