Respuesta :

Answer is: A;
Re-arrange formula to give: sin q = -1/square root of 2
Now, sin (3 pie/4) = sin(135) = -1/square root of 2
Also, sin(5 pie/4) = sin(235) = -sin(45) = -1/square root of 2

rearrange the equation we get;

sinq = -2/2sqrt(2) = -1/sqrt(2)

answer is letter A. 3pi/4 , 5pi/4


Hope this helps your question! Goodluck
