Remember, even if you enter an answer rounded to a set number of decimal places, if
you use that number in a future calculation, you should use all of the decimal places
reported on your calculator!
Solve triangle ABC if ZA = 40.8°, a = 185.1, and b = 248.6.
sin B = .87758
(round answer to 5 decimal places)
There are two possible angles B between 0 and 180° with this value for sine. Find the two angles, and
report them so that B₁ is the acute angle.
