A= ? ft2

2.) UseFigure 1to evaluate the trigonometric function. Enter the exact answer. Image attached (Figure Triangle)

tanA = ?

3.) Find the exact value ofsin(/3)

sin(pi/3) = ?

4.) Use reference angles to evaluatesec(19/6) Enter the exact answers.

For the number, either choosefrom the bar at the top or type in Pi (with a capital P).

The reference angle is ?

sec(19/6) = ?

Please Explain on all of these so I can better understand what I am doing! Thank you.
