Question

will reward medal/fan! (:
solve the equation
(sin(90 degrees-x) ) / sinx = -sqrt 3
x E (-270, 270)

Answer 1

one approach
Sin (a - b) = Sin a Cos b - Cos a Sin b
a = 90 and b = x
sin 90 = 1 Cos 90 = 0
divide through by Sin x
Cos/Sin = -rt 3
reference unit circle

Answer 2

thank you! i figured it out. thank you very much
