Check the picture below, that one in the picture is just an example of the correspondence of sine and cosine in a right-triangle, in this case, we're in the 0° < x < 90°, so in the I Quadrant, and thus we have a right-triangle.
to make it short, sin(90° - 19°) = cos(19°), or that is sin(71°), thus x = 71.
Expand first and then move all the x terms to one side.
make sure when u are moving the x terms flip the sign AND inequality sign.
36 is what I got for this question
