Error in London Eye Applied Trig Problem

The formula for the needed angle is using tan. However the denominator should use the length of the hypotenuse not the opposite side. Test using the given sides, and the sin function to compute the smaller angle and then compute the needed angle by subtracting 90 plus the small angle from 180.

Thanks for sharing this work, a very handy review.

A plethora of [Math Processing Error] messages

Unfortunately, many of the diagrams, formulas, and solutions are not displaying correctly. Every page of the book I've used so far (I'm only doing the chapters on trig) is littered with the message [Math Processing Error] in red font. Thank you for this free textbook by the way it is super helpful!
