Answer:

60°

Step-by-step explanation:

Sum of angles of triangle = 180°

x + 40 + 80 = 180

x + 120 = 180 {Subtract 80 from both sides}

x = 180 - 120

x = 60°

Is d y / d x the exact same as f ' ( x ) ? If yes, which is more commonly used?

Murrr4er [49]

It's dependent on the context. A book may ask you to find the f'(x) of a function and you may have to use a u sub in your problem which requires you to find the dy/dx of what you substitute. So in this case both would be used.
