Find angle A if it is greater than or equal to 0 degrees and smaller than or equal to 180 degrees. round to the nearest tenth of a degree, if necessary.
a) sinA = 0.5
b) cosA = 0.5
e) cosA = 0.4561
g) sinA = 0.5736
PLEASE HELP WID THIS!!:( i tried so much! but im not getting it...
Thanks I greatly appreciate it sooo much!!:)

If sin A = 0.5, doesn't that make A = 30 degrees. That is >0 and <180 so it qualifies. Just punch in the other numbers on your calculator and read the angle A. See if it meets the criteria.

That  slipped in. Sin A = 0.5; A = 30 degrees and not 30 degrees.
