Quiz: Expressing Angles Using Inverse Trigonometric Function

In the applet below, use INVERSE TRIGONOMETRIC FUNCTIONS to write EXACT EXPRESSIONS for the measures of the acute angles (A and B) in the right triangle displayed. Be sure to enter EXACT VALUES (and not decimal approximations). You should be able to write the measure of each angle in 3 DIFFERENT WAYS. To clear any entered expression at any time, simply click the "Reset Answer" button. If you enter a correct expression for any angle, the applet will indicate this to you.
