Question

Find an angle between 0 and 2π that is coterminal with -3π /10

Answer 1

17π/10

Explanation:

To find a co-terminal angle in a specific range, add or subtract multiples of 2π until you have an angle in the desired range. Here, you can add 2π.

-3π/10 +20π/10 = 17π/10 . . . . angle co-terminal with -3π/10
