we did a chart and
sinx=sin(180-x)
cosx=cos(180-x)
tanx=tan(180-x)
There are relationships between the value of a primary trigonometri ratio for an acute angle and the value of the same primary trigonometric ratio for the supplement of the acute angle.
We used sin and cosine laws to determine the sine lengths and angle measures in acute oblique triangles.
