Now, you try. Complete the Think & Click activity by looking at each problem below, thinking about it, and then clicking on the question to reveal the solution.
Given sin A = .98 solve for A in degrees.
Make sure your calculator is set on degrees.
sin A = 0.98
A = sin-1(0.98)
A ≈ 78.52°
Solve for angle B in radians.
Make sure your calculator is set on radians.
cos B = 
B = cos-1
≈ 1.32 radians
