Use a reference angle to write sin (35pi/36) in terms of the sine of a positive acute angle

Step-by-step explanation:

hello:

note : for all x in ℝ : sin (π - x) = sinx

35π/36 = (36π - π) / 36 = 36π / 36 - π/36

35π/36 = π - π/36

use the note : sins (35π/36) = sin (π - π/36) = sin (π/36)

positive acute angle is : π/36
